(Well, one exception: a reference to a "sling-ended catapult" used in aerial combat in Vol-3). It does appear in Supplement I in the damage table (1d4 points vs. man-size, p. 15) and corrections list ("All hobbits add  +3  to hit probabilities when using the sling", p. 68). But without anywhere the rules giving them a range, rate of fire, or cost, it's a bit of a murky issue. In AD&D Gygax gave them a range in between that of a short- or longbow, and a rate of fire half that of bows. I wanted to do some research to make sure that was dialed in correctly for my games.<br /> <br /> The amazing thing is that numerous sources state that slings had a rate of fire at least as fast as bows, and a range that likely exceeded them, with a heavier and faster projectile, that was possibly more accurate and more damaging. How can this be? Of course, you also have the case of the crossbow with clearly deficient rate of fire, and thus borderline useless in standard D&D play. And yet at a late point it was favored over the bow. Why?<br /> <br /> Among other resources, I came across a very nice article by Chris Harrison (Assistant Professor at Carnegie Mellon Human-Computer Interaction Institute), originally published in The Bulletin of Primitive Technology (2006). Near the conclusion he writes: <br /> <br /> <blockquote class="tr_bq"> <i>When looking at the evolution of ranged weapons, there is a trend towards increasingly simple operation. The sling requires enormous skill, one that can generally only be obtained with training from childhood (Hawkins, 1847; Korfmann, 1973; Wise, 1976; Ferrill, 1985). Without this mastery, a person armed with the weapon would be practically useless. The sling is exceptionally difficult to aim because it is being rotated when fired. It is common for people to fire projectiles backwards when they are first learning, meaning a high degree of proficiency is needed before they can be safely placed in a battlefield situation. On the other hand, the bow could be taught at any point in life, and be deadly with minimal experience. The bow does not suffer from the sling’s accuracy problems because of its ability to be drawn and then aimed. However, archers did have to be strong, which increased the required training time (Wise, 1976). The development of the crossbow with a mechanical device to cock the weapon enabled anyone to use it and have the ability to kill even an armored soldier at distance. The crossbow was the first true ‘point-and-shoot’ weapon, as it could be cocked and then easily aimed using the large stock. Although much slower to reload than bows, it was seen as an acceptable tradeoff for the ease-of-use gained. The shift to firearms was similar. They were even slower than the already sluggish crossbow, at least at first. However, the operation was simple and there was no physical strength needed to load the weapon. Also, its ‘point-and-shoot’ nature made someone with almost no experience immediately useful on the battlefield, and very deadly. This evolution occurred primarily because of changes in military and governmental organization. In feudal times, lords could recruit their serf population as soldiers (Wise, 1976). Many of these men were already proficient with the bow or sling, which were used for hunting game. However, by the High Middle Ages, nations and cities had developed large standing armies, which were recruited, sustained, and equipped by the government (Martin, 1968). An increasing number of these recruits were from urban populations which had far less exposure to ranged weapons. These units had to be trained from scratch and there was a high turnover. This led to the increased use of weapons that were deadlier with less training. The sling was perhaps the least effective choice of ranged weapon in this role.  </i></blockquote> <br /> <a href="http://chrisharrison.net/index.php/Research/Sling">See the full article here</a>. We might phrase that observation in economic terms; the advance of missile weapons was to get cheaper and faster -- lower quality, but able to be fielded in larger numbers and in that way more powerful. (We might well look to many things in our own era that became dominant by virtue of being crappier but cheaper: MP3 audio encoding, travel agencies, car ride services, etc.) Gygax actually makes much the same observation in an article in <i>Strategic Review</i> #7, "The Missile Weapon in Classic Warfare". (!)<br /> <br /> That said, this is not something that D&D models very well. By default Fighters simply have proficiency in all weapon types. If the sling were the best missile weapon in an expert's hands, then every Fighter would be carrying slings and nothing else. If we want our game to look like the medieval era that would be a bit jarring. In any heroic story, the protagonist uses the weapon common to his people; e.g., David with his sling, Robin Hood with his longbow, William Tell with his crossbow, etc. <br /> <br /> So in lieu of modelling more ancient/personalized weapons as taking greater amounts of training time and commitment, AD&D reverses the statistics to make sure that slings are a deficient choice for adventurers. What could we do to give slings their real-life fire rate and range (and advantages in small size, low weight, conceal-ability, etc.) without their completely eliminating the use of bows by PC adventurers? Or would that actually be acceptable?<br /> <br /> <div style='clear: both;'></div> </div> <div class='post-footer'> <div class='post-footer-line post-footer-line-1'> <span class='post-author vcard'> Posted by <span class='fn' itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://www.blogger.com/profile/00705402326320853684' itemprop='url'/> <a class='g-profile' href='https://www.blogger.com/profile/00705402326320853684' rel='author' title='author profile'> <span itemprop='name'>Delta</span> </a> </span> </span> <span class='post-timestamp'> at <meta content='http://deltasdnd.blogspot.com/2017/05/slings-and-arrows-and-outrageous.html' itemprop='url'/> <a class='timestamp-link' href='http://deltasdnd.blogspot.com/2017/05/slings-and-arrows-and-outrageous.html' rel='bookmark' title='permanent link'><abbr class='published' itemprop='datePublished' title='2017-05-29T05:00:00-04:00'>05:00</abbr></a> </span> <span class='post-comment-link'> <a class='comment-link' href='http://deltasdnd.blogspot.com/2017/05/slings-and-arrows-and-outrageous.html#comment-form' onclick=''> 53 comments: </a> </span> <span class='post-icons'> <span class='item-control blog-admin pid-1403267436'> <a href='https://www.blogger.com/post-edit.g?blogID=2170237526012357403&postID=8262602552918411825&from=pencil' title='Edit Post'> <img alt='' class='icon-action' height='18' src='https://resources.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/> </a> </span> </span> <div class='post-share-buttons goog-inline-block'> </div> </div> <div class='post-footer-line post-footer-line-2'> <span class='post-labels'> </span> </div> <div class='post-footer-line post-footer-line-3'> <span class='post-location'> </span> </div> </div> </div> </div> </div></div> <div class="date-outer"> <h2 class='date-header'><span>2017-05-22</span></h2> <div class="date-posts"> <div class='post-outer'> <div class='post hentry uncustomized-post-template' itemprop='blogPost' itemscope='itemscope' itemtype='http://schema.org/BlogPosting'> <meta content='2170237526012357403' itemprop='blogId'/> <meta content='3274047672574129390' itemprop='postId'/> <a name='3274047672574129390'></a> <h3 class='post-title entry-title' itemprop='name'> <a href='http://deltasdnd.blogspot.com/2017/05/guest-post-medieval-magic.html'>Guest Post: Medieval Magic</a> </h3> <div class='post-header'> <div class='post-header-line-1'></div> </div> <div class='post-body entry-content' id='post-body-3274047672574129390' itemprop='articleBody'> <i>I think this is the first-ever guest post on this blog. In an online discussion a few weeks back, Landon Schurtz made what I thought was a fascinating comment about the spell list he uses in his low-magic D&D campaign. A problem might arise in determining spells appropriate for that milieu. Solution: Why not use his copious literary skills to find and read up on actual medieval grimoires and see what writers of the time thought was really possible? Notice again how this links to our project of using real-life research to actually simplify the game (three weeks ago); and also to craft a set of wilderness rules to fix the blindspots from original D&D (last two weeks).</i><br /> <i><br /></i> <i>Landon Schurtz is a professor of philosophy and a roleplayer for the last thirty-plus years, not in that order. He is currently working on a never-to-be-completed project to build the "perfect" fantasy roleplaying system by cannibalizing pieces and parts from various "old-school" games.</i><br /> <br /> <hr /> <br /> <div style="line-height: 108%; margin-bottom: 0.11in;"> It started with <i>Leomund’s tiny hut</i>.</div> <div style="line-height: 108%; margin-bottom: 0.11in;"> In AD&D, <i>Leomund’s tiny hut</i> is a very useful spell for adventuring magic-users to learn, as it allows creation of effective shelter when traveling. I’ve played many magic-users in my day, and they all acquired the spell as soon as possible – it just made good sense for a traveling spellcaster to have it. And therein lay the problem.</div> <div style="line-height: 108%; margin-bottom: 0.11in;"> Even without dealing with the longer-lasting (and thus more effective) versions available in later editions of the game, I quickly became annoyed that <i>Leomund’s</i> <i>tiny hut</i> was <i>too</i> effective – its existence allowed parties to sidestep certain challenges that seemed to me to be integral to the kind of game I was trying to run, which, in this case, was the kind of game where player characters, no matter how high and mighty, could never fully insulate themselves from the basic threats of a pseudo-medieval setting. I wanted travel to be arduous and chancy, food and water to be precious, and so on. In short, I wanted my games to <i>feel </i>more “medieval,” something closer to low fantasy than high.</div> <div style="line-height: 108%; margin-bottom: 0.11in;"> So it was that several campaigns ago I began going through the spell lists and eliminating certain spells. Those that made travel a non-issue or something very close, like <i>Leomund’s tiny hut</i> and <i>teleport</i>, were the first to go; next followed spells that eliminated the need to think about rations and foraging, such as <i>create food and water</i>; and so on. Eventually, I even eliminated all <i>cure...wounds </i>spells from my game, though I “replaced” them with a different hit point mechanic that rewarded tactical retreat by allowing characters who were not below half hit points to recover fully in just a few minutes.</div> <div style="line-height: 108%; margin-bottom: 0.11in;"> Though this method was getting good results in general, I still felt I could do a better job of getting a “real medieval feel” for my world, so I took a different approach: I went back to the sources. I conducted a fair bit of research on beliefs about magic in the Middle Ages, starting with scholarly works like Richard Kieckhefer’s indispensible <i>Magic in the Middle Ages</i> and eventually moving on to what proved to be my definitive resources, actual medieval grimoires.</div> <div style="line-height: 108%; margin-bottom: 0.11in;"> Books like <i>Liber Juratus</i> and <i>Sword of Moses</i>, which date to the 13<sup>th</sup> and 10<sup>th</sup> centuries, respectively, can be found in digital format at www.esotericarchives.com, a useful resource for anyone looking to inject a little authenticity into their games. I began perusing these and other grimoires in an effort to see what a “real” medieval wizard would have been (thought) capable of, and I was pleasantly surprised to find that many spells in AD&D had “genuine” parallels – the <i>Sword of Moses</i> purports to hold the secrets of how to cast spells that would equate to <i>protection from fire</i>, <i>silence</i>, and <i>blindness</i>, and <i>Liber Juratus</i> describes incantations that could credibly be translated in game terms as <i>telekinesis</i>, <i>phantom steed</i>, and even <i>Drawmij’s instant summons</i>!</div> <div style="line-height: 108%; margin-bottom: 0.11in;"> Using these, I was able to construct spells lists that I feel have a real “medieval” flavor. Magic-users still have considerable power, though they have much-reduced capacity to deal direct damage. Gone are high-fantasy staples like <i>magic missile</i> and <i>fireball</i>, but in their place, wizards gain many abilities previously restricted to illusionists, clerics, and even druids. I have divided the spells into four categories: thaumaturgy, which I take to be the “default” sort of magic employed by magic-users; elven magic, which, as the name implies, is the kind of magic employed by elven spell-casters and rarely taught to outsiders (I haven’t decided whether elves can also use thaumaturgy or are restricted to elven magic alone); black magic, which encompasses most “evil” magic; and white magic, wherein one finds the spells of binding and banishing extraplanar creatures. Except for the division between elven magic and everything else, this choice was made more for organizational purposes – I originally included white and black magic on the main thaumaturgy list, though perhaps a DM might allow for certain villains to have access to black magic only, thanks to, say, a demonic pact.</div> <div style="line-height: 108%; margin-bottom: 0.11in;"> A few notes:</div> <ul> <li> <div style="line-height: 108%; margin-bottom: 0.11in;"> I do not use clerics or druids in my games, nor illusionists, now that I have this new spell list. The thaumaturgy list has many spells that were once the province of one of those three classes.</div> </li> <li> <div style="line-height: 108%; margin-bottom: 0.11in;"> The vast majority of spells are taken from the <i>PHB </i>and <i>UA</i>, while a few (mostly in the elven magic section) come from <i>Oriental Adventures</i>, which has a wide selection of “elemental” spells. The various “undead production” spells come from the description of the Death Master class, in <i>Dragon </i>magazine; for DMs who would prefer to just use <i>animate dead</i>, the switch could easily be made.</div> </li> <li> <div style="line-height: 108%; margin-bottom: 0.11in;"> All spells function as described in the books except <i>cure disease</i> – in this system, a different <i>cure [disease] </i>spell is needed for each ailment. </div> <div style="text-align: center;"> <br /> <span style="font-size: large;"><a href="http://www.superdan.net/download/blog/deltasdnd/LandonsRevisedSpellLists.pdf">Download Landon's revised spell list here!</a></span></div> </li> </ul> <br /> <br /> <div style='clear: both;'></div> </div> <div class='post-footer'> <div class='post-footer-line post-footer-line-1'> <span class='post-author vcard'> Posted by <span class='fn' itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://www.blogger.com/profile/00705402326320853684' itemprop='url'/> <a class='g-profile' href='https://www.blogger.com/profile/00705402326320853684' rel='author' title='author profile'> <span itemprop='name'>Delta</span> </a> </span> </span> <span class='post-timestamp'> at <meta content='http://deltasdnd.blogspot.com/2017/05/guest-post-medieval-magic.html' itemprop='url'/> <a class='timestamp-link' href='http://deltasdnd.blogspot.com/2017/05/guest-post-medieval-magic.html' rel='bookmark' title='permanent link'><abbr class='published' itemprop='datePublished' title='2017-05-22T05:00:00-04:00'>05:00</abbr></a> </span> <span class='post-comment-link'> <a class='comment-link' href='http://deltasdnd.blogspot.com/2017/05/guest-post-medieval-magic.html#comment-form' onclick=''> 25 comments: </a> </span> <span class='post-icons'> <span class='item-control blog-admin pid-1403267436'> <a href='https://www.blogger.com/post-edit.g?blogID=2170237526012357403&postID=3274047672574129390&from=pencil' title='Edit Post'> <img alt='' class='icon-action' height='18' src='https://resources.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/> </a> </span> </span> <div class='post-share-buttons goog-inline-block'> </div> </div> <div class='post-footer-line post-footer-line-2'> <span class='post-labels'> </span> </div> <div class='post-footer-line post-footer-line-3'> <span class='post-location'> </span> </div> </div> </div> </div> </div></div> <div class="date-outer"> <h2 class='date-header'><span>2017-05-20</span></h2> <div class="date-posts"> <div class='post-outer'> <div class='post hentry uncustomized-post-template' itemprop='blogPost' itemscope='itemscope' itemtype='http://schema.org/BlogPosting'> <meta content='2170237526012357403' itemprop='blogId'/> <meta content='5509998082731484614' itemprop='postId'/> <a name='5509998082731484614'></a> <h3 class='post-title entry-title' itemprop='name'> <a href='http://deltasdnd.blogspot.com/2017/05/how-to-include-justifications-in-rules.html'>How to Include Justifications in a Rules Document?</a> </h3> <div class='post-header'> <div class='post-header-line-1'></div> </div> <div class='post-body entry-content' id='post-body-5509998082731484614' itemprop='articleBody'> As a final thought to the wilderness rules ideas the last two weeks: You'll notice that each of the separate sections had an appendix of notes and references for different rules at the bottom of each page.<br /> <br /> This is something I struggle with a lot in the context of paper rules documents. You want the rules to be terse, be immediately interpretable in play, and be easy to memorize. But on the other hand I think it's useful to include specific justifications, motivations, and references; I have the feeling that without those, I (and maybe many others) wind up repeating the same research projects over and over again, often recreating the same conclusions as other game designers. Now, those justifications may actually be longer than the rules themselves. My <a href="http://www.oedgames.com/">OED House Rules</a> document has copious sidebar annotations (invisible in the distributed PDF form), likely longer than the rules themselves.<br /> <br /> So I ask: What's the best way to include reference/citation/justifications in a rules document? Sidebar notes on each page? Footnotes? A block of references in each section? A consolidated appendix of commentary at the back of the book? A separate supplemental document entirely? Hyperlinks to multiple outside articles?<br /> <br /> <br /> <div style='clear: both;'></div> </div> <div class='post-footer'> <div class='post-footer-line post-footer-line-1'> <span class='post-author vcard'> Posted by <span class='fn' itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://www.blogger.com/profile/00705402326320853684' itemprop='url'/> <a class='g-profile' href='https://www.blogger.com/profile/00705402326320853684' rel='author' title='author profile'> <span itemprop='name'>Delta</span> </a> </span> </span> <span class='post-timestamp'> at <meta content='http://deltasdnd.blogspot.com/2017/05/how-to-include-justifications-in-rules.html' itemprop='url'/> <a class='timestamp-link' href='http://deltasdnd.blogspot.com/2017/05/how-to-include-justifications-in-rules.html' rel='bookmark' title='permanent link'><abbr class='published' itemprop='datePublished' title='2017-05-20T05:00:00-04:00'>05:00</abbr></a> </span> <span class='post-comment-link'> <a class='comment-link' href='http://deltasdnd.blogspot.com/2017/05/how-to-include-justifications-in-rules.html#comment-form' onclick=''> 27 comments: </a> </span> <span class='post-icons'> <span class='item-control blog-admin pid-1403267436'> <a href='https://www.blogger.com/post-edit.g?blogID=2170237526012357403&postID=5509998082731484614&from=pencil' title='Edit Post'> <img alt='' class='icon-action' height='18' src='https://resources.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/> </a> </span> </span> <div class='post-share-buttons goog-inline-block'> </div> </div> <div class='post-footer-line post-footer-line-2'> <span class='post-labels'> </span> </div> <div class='post-footer-line post-footer-line-3'> <span class='post-location'> </span> </div> </div> </div> </div> </div></div> <div class="date-outer"> <h2 class='date-header'><span>2017-05-18</span></h2> <div class="date-posts"> <div class='post-outer'> <div class='post hentry uncustomized-post-template' itemprop='blogPost' itemscope='itemscope' itemtype='http://schema.org/BlogPosting'> <meta content='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhYxYGV5n_5fUoiY2zoGDzKIyzdOZ0Rc4basyr0ElrkdioSH1F2dZ9LTtMhKcH5RQeF2nVMJi8KckJy9lsx6ptIoGtOU0IMRMA9FKleVZn-4-k8eXcq-8fmM4g6SmykrGwtgA6qaNr0TvRJ/s1600/WeatherEvents.png' itemprop='image_url'/> <meta content='2170237526012357403' itemprop='blogId'/> <meta content='5460593785818035190' itemprop='postId'/> <a name='5460593785818035190'></a> <h3 class='post-title entry-title' itemprop='name'> <a href='http://deltasdnd.blogspot.com/2017/05/oed-wilderness-rules-draft-weather.html'>OED Wilderness Rules Draft: Weather Events</a> </h3> <div class='post-header'> <div class='post-header-line-1'></div> </div> <div class='post-body entry-content' id='post-body-5460593785818035190' itemprop='articleBody'> The fourth and final part of a draft of modified wilderness adventuring rules for OED-style games. Something like this was playtested at Helgacon this year. The principal feature it that it exchanges the daily Lost die for a simple Weather mechanic. Whereas in the past I've struggled in Sisyphean style with super-complicated weather rules (e.g.: <i>Dragon</i> #68 "Weather in the World of Greyhawk", <i>AD&D Wilderness Survival Guide</i>), this simple d6 roll is making me perfectly happy in play now.

Thus two dice a rolled each day: a red die (for Encounters) and a blue die (for Weather). On a roll of 5-6 some weather Event occurs; consult the table to the right. The default situation assumes a temperate environment in the summer, with a base daily temperature of Warm (clo 0). </div> <div style="line-height: 100%; margin-bottom: 0in;"> <br /></div> <div style="line-height: 100%; margin-bottom: 0in;"> <u>Heat Wave:</u> Daily temperature is Hot (clo –1).

We downloaded daily historical weather data for these months 2001-2009 and computed statistics as above. Paris was chosen as central to battles in the Hundred Years War. Technically, a d8 Event die would be more realistic (1-in-8 heat wave, 2-in-8 thunderstorm), but the d6 was used above for simplicity in play. <a href="https://www.wunderground.com/history/">https://www.wunderground.com/history/</a></div> </li> <li> <div style="line-height: 100%; margin-bottom: 0in;"> Frequency of rainy days may be 25-50% in Atlantic region, northern Europe.

In this part we connect levels of clothing, and hence comfortable ranges for temperature, to real-world "clo" thermal insulation measurements. While a very rough approximation of real-world research, having completed it, I find that this pretty accurately maps to my mental process for getting dressed on my way to the college where I work (which entails walking & waiting for city bus, usually outdoors for at least 30 minutes each way).

(Or in other words: the modern 20% rule-of-thumb is highly conservative, kind to the animal, and has a large safety overhead built-in). This results in our 60-90-120 stone horses having light-load cutoffs at 20-30-40 stone, which seems to work pretty well, and happen to be quite close to the Original D&D numbers. <a href="https://deltasdnd.blogspot.com/2023/07/how-much-weight-can-horse-carry-in-d.html">See here for more.</a><br /></div> <div style='clear: both;'></div> </div> <div class='post-footer'> <div class='post-footer-line post-footer-line-1'> <span class='post-author vcard'> Posted by <span class='fn' itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://www.blogger.com/profile/00705402326320853684' itemprop='url'/> <a class='g-profile' href='https://www.blogger.com/profile/00705402326320853684' rel='author' title='author profile'> <span itemprop='name'>Delta</span> </a> </span> </span> <span class='post-timestamp'> at <meta content='http://deltasdnd.blogspot.com/2017/05/oed-wilderness-rules-draft-carrying.html' itemprop='url'/> <a class='timestamp-link' href='http://deltasdnd.blogspot.com/2017/05/oed-wilderness-rules-draft-carrying.html' rel='bookmark' title='permanent link'><abbr class='published' itemprop='datePublished' title='2017-05-11T05:00:00-04:00'>05:00</abbr></a> </span> <span class='post-comment-link'> <a class='comment-link' href='http://deltasdnd.blogspot.com/2017/05/oed-wilderness-rules-draft-carrying.html#comment-form' onclick=''> 18 comments: </a> </span> <span class='post-icons'> <span class='item-control blog-admin pid-1403267436'> <a href='https://www.blogger.com/post-edit.g?blogID=2170237526012357403&postID=7763604412329521601&from=pencil' title='Edit Post'> <img alt='' class='icon-action' height='18' src='https://resources.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/> </a> </span> </span> <div class='post-share-buttons goog-inline-block'> </div> </div> <div class='post-footer-line post-footer-line-2'> <span class='post-labels'> </span> </div> <div class='post-footer-line post-footer-line-3'> <span class='post-location'> </span> </div> </div> </div> </div> </div></div> <div class="date-outer"> <h2 class='date-header'><span>2017-05-08</span></h2> <div class="date-posts"> <div class='post-outer'> <div class='post hentry uncustomized-post-template' itemprop='blogPost' itemscope='itemscope' itemtype='http://schema.org/BlogPosting'> <meta content='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiR9Wbx4enK_R_vo1uXy7aOdjAS2ONsBYyGTaJ7xbDsyZ9Qq5DjH7F_T-ywavOpeBMM1vWJZNOE3hMIa4AYVQxxzsOrDPYjn-7uJPWOPPWuqzM4jZQuCA7U6T6dFjIignLAnurkwaITeFCd/s1600/SupplyCosts.png' itemprop='image_url'/> <meta content='2170237526012357403' itemprop='blogId'/> <meta content='2006886141685024182' itemprop='postId'/> <a name='2006886141685024182'></a> <h3 class='post-title entry-title' itemprop='name'> <a href='http://deltasdnd.blogspot.com/2017/05/oed-wilderness-rules-draft-food-and.html'>OED Wilderness Rules Draft: Food and Water</a> </h3> <div class='post-header'> <div class='post-header-line-1'></div> </div> <div class='post-body entry-content' id='post-body-2006886141685024182' itemprop='articleBody'> In the last year, I've spent some tweaking wilderness adventuring rules to make myself happy. Although OD&D's rules were based partly on <i>Outdoor Survival</i> it has numerous blind spots; like having no mechanics for running out of food or water, reduced movement rates, weather, etc. (things that were at the very core of <i>Outdoor Survival</i> play). Partly what I'm doing here is bringing in some more parts of O.S., looking in places to real-world research on certain effects (re: last week's post), and shaving off the hard edges to make it more streamlined and easier to run in play.

The first wargame I ever picked up as a kid was Avalon Hill's <i>Bismark</i>. Among the first video games I got hooked on was Sid Meiers' <i>Pirates!</i>. I'm always looking for the perfect D&D naval experience but haven't found it yet. The naval combat rules in OD&D Vol-3 (p. 28-35) are as close as I've found to date, but they have issues -- like (a) the move rates being scaled to around 2 or 3 feet per turn (so that ships zip across the board space in just a single turn), (b) the reference that melee be done by "Man-to-Man rules as found in CHAINMAIL" (so every individual man needs to be moved and rolled for attacks separately), etc. <br /> <br /> As part of my continuing search, I recently, at long last, acquired a copy of the rules to Gygax & Arneson's first-ever game collaboration, <i>Don't Give Up the Ship </i>(DGUTS below)<i>.</i> This is the 2nd Edition (1975), with added optional rules from Mike Carr (designer of <i>Fight in the Skies</i>, referenced in OD&D as inspiration for its detailed aerial combat rules). It's a great read, obviously made with a ton of love and affection to the milieu of fighting ships of the American Revolutionary period; and in very much the same style as a book like <i>Chainmail</i>. In some sense it has about what you'd expect: a Basic Game, optional Advanced Rules, super-detailed Single-Ship Action Rules, more abstracted Fleet Action Rules, rosters of possible ship-to-ship engagements (all historically based), a Bibliography of over a dozen historical texts, etc. The play involves tracking gun weights, wind direction & force (reminiscent of many tables in D&D), sailing points and gunnery with a protractor, and so forth. Boarding is entirely abstracted, with the mechanic based purely on opposed morale checks (and without any men being lost from such actions in the standard rule). Some of the DNA can even be detected in <i>Swords & Spells</i>; like, the overall format of the record sheet, and the percentage-based damage adjustments that likely require a calculator (e.g., the last ship-to-ship optional rule notes that "Various tests made have proved beyond reasonable doubt that U.S. shot was lighter than it should be", and so should do a proportional 7% less damage; whereas French shot was 10% heavier and therefore will do 10% more damage). <br /> <br /> It's not immediately clear how this can benefit your D&D game, however. One thing I noticed is that the scale is wisely chosen: 1" = 100 yards, 1 turn = 5 minutes. It recommends ship models close 1: 1200 scale (note this varies from the surface equivalent to scale of 1: 3600, but by less than an order of magnitude). This is quite different from the D&D scale officially 1" = 10 yards, or arguably what should have been 1" = 5 feet to match the size of miniatures in Man-to-Man action. Yet despite this, OD&D recommends the same 1: 1200 scale for ships as DGUTS (Vol-3, p. 30), which is either 3 or 20 times too small depending on how you count that. (As an aside, we can reflect here how much earlier wargaming relied on the player to acquire or build their own materials from other products, as the rules were designed expecting toys like that to be commercially available; this is long before consolidated brands in which wargame rules are part of a company selling their own boxed products.) <br /> <br /> The really startling thing (to modern eyes) is none of that, however. First let me observe that DGUTS seems to owe a rather large inspiration and debt to a halfway famous older game, <i>Fletcher Pratt's Naval War Game</i> (published in 1943, but developed and played for more than a decade before that). Pratt's game simulates fighting ships contemporaneous to its play in the era between the World Wars. The intriguing thing that Pratt did with it is to rely on the real-world publication of <i>Jane's Fighting Ships</i> for its ship statistics. I wouldn't know much about Pratt's game it weren't for Jon Peterson's sublime <i>Playing at the World</i>. Peterson writes (p. 280):<br /> <br /> <blockquote class="tr_bq"> <i>Pratt borrowed Jane's method of classifying ships, especially his notation for measuring arms and armor. The thickness of armor and the size of guns are quantified and compounded in an elaborate mathematical formula, to which additional figures are added for amenities like torpedoes or the ability to carry aircraft. This sum is multiplied by the speed of the vessel in knots, and finally the tonnage is added to determine a "value" for the ship. Ship values tend to be large; one example boat given in the rules has a value of 23,034. Guns, when they score a hit with a shell, inflict a certain number of points of damage depending on their size; the weakest 37mm guns might inflict 23 points of damage, the standard 4.7" cannon hits for 244 damage, while the implausibly large 16" cannon deals a whopping 10,550 points of damage. As a ship suffers points of damage, it begins to lose capabilities, including movement speed and the use of its guns. For the convenience of players, a "ship card" typically lists all of these attributes and details exactly which capacities are sacrificed at the various levels of disrepair. When it has taken damage greater than or equal to its value, a ship is sunk. </i></blockquote> <br /> Gygax & Arneson's (and Carr's) <i>Don't Give Up the Ship</i> uses the same basic idiom, somewhat simplified, for its ship statistics. Two types of damage are tracked: high (sails & masts) and low (deck and hull). The high damage score is simply half the real-world ship's actual tonnage, with these points split proportionally among each individual sail and mast on the actual vessel -- lose a sufficient number of points, and sails/masts are lost, reducing speed appropriately. The low damage is equal to the real-world ship's tonnage -- when damage scored is over 70%, the vessel may possibly sink slowly, while at 100% the vessel sinks automatically; in addition, crewmen are lost proportionally following any low damage scored. Specifically: "crew factors" (CF) are tracked where a ship has one CF for every 21 men on the real-world ship (a seemingly odd conversion rate, but this comes from an estimated 7 men to operate a gun, times 3 guns per fire unit; see p. 17 and below). <br /> <br /> Likewise, guns are based on whatever guns the real-world ship was known to have. For example: Ship A in the simple "Training Game" scenario has 12 24-pound guns, 15 12-pound guns, and 3 9-pound guns (denoted 12-24#, 15-12#, 3-9#). Every 3 guns of a given type allows one "fire factor", that is, one d6 roll on the very simple combat table per turn (which can result in either a high or low hit or a miss, depending on range). Damage is simply equal to the poundage of the gun type firing -- for example, one hit from a trio of of 12-pound guns does 12 points of damage. In its way, a breathtakingly elegant mechanic!<br /> <br /> The thing that I like about these systems is that by making an explicit connection/formula between real-world entities and game entities, the designers have immediately populated their game world with <i>everything</i> (of the appropriate category) in one fell swoop. Pratt doesn't need to include rosters of ships; he can just direct the reader to <i>Jane's Fighting Ships</i>, or other reference works. The ship rosters in Gygax & Arneson's DGUTS aren't really game statistics, they're just real-life profiles of historical ships (in terms of real tonnage, guns, crew, etc.). The designer doesn't have to spend time laboring over individual game-piece statistics. One's game is enriched by, and stands on the shoulders of, the amount of attention and detail given by military scientists tracking and documenting the things in the real world. If any balancing or revisions are needed, they are only in the game rules themselves (perhaps tweaking the mathematical formulae that simulate ships in the game). <br /> <br /> Note how briskly this tacks against the fantasy gaming headwind that attention to simulating concrete, real-world elements cannot have any benefit (<a href="http://deltasdnd.blogspot.com/2016/10/nothing-remains-interesting-if-anything.html">link</a>). And how synchronized it is with our long-running observation that real-world solutions almost always give the most elegant in-game mechanics (<a href="http://deltasdnd.blogspot.com/2010/03/realism-in-game-design.html">link</a>). In fact, by making the link explicit and mathematically precise, we instantly profit by the whole universe of whatever real-world thing we have simulated.<br /> <br /> Of course, this assumes that there is a pre-existing compendium of measurable information compiled about our topic of inquiry, which we have in abundance for fighting ships -- and much less so for individual people, arms, creatures, or of course fantasy creatures. But I am tempted to think about what other quantitative fields of study exist that we can port semi-immediately, and connect explicitly, into our D&D games to their benefit. Let's be on the lookout for that in the next few weeks.<br /> <br /> Can you think of any such field of study that we can mathematically connect to our D&D games in order to enrich them?<br /> <br />
