17 | ||
18 | For the sake of brevity in the following descriptions, character ability | |
19 | scores, and the usual modifiers are described using the notations shown in | |
20 | tables~\ref{tab:ability-abbr} and \ref{tab:ability-mods}. | |

55 | \section{Experience and advancement} | |
56 | ||
57 | \begin{enumerate} | |
58 | ||
59 | \item Bonus experience points for high prime-requisite ability scores are | |
60 | \emph{not} awarded. Characters with strong PRs are already at an advantage | |
61 | and shouldn't also make accelerated progress through levels. | |
62 | ||
63 | \item Experience points are \emph{not} awarded to characters on the basis of | |
64 | treasure obtained. It's hard to see why characters should be rewarded | |
65 | merely for stuffing gold down their trousers. | |
66 | ||
67 | \item To compensate for this, experience points for monsters defeated are | |
68 | multiplied by 5. | |
69 | ||
70 | \item Experience points for monsters defeated are calculated according to the | |
71 | revised table in the \emph{Master} set. | |
72 | ||
73 | \end{enumerate} | |
74 | ||
75 | ||
76 | \section{Character classes} | |
77 | ||
78 | \begin{enumerate} | |
79 | ||
80 | \item Player characters may be Mystics; neutral Clerics may become Druids at | |
81 | level~9. | |
82 | ||
83 | \end{enumerate} | |
84 | ||
85 | ||
86 | \section{Magic and ability scores} | |
87 | ||
88 | In order to reward spell-casters with strong PR scores, their spells are | |
89 | strengthened as follows. (Recall that $P$ stands for the character's prime | |
90 | requisite.) | |
91 | ||
92 | \begin{enumerate} | |
93 | ||
94 | \item Dice (up to $\dice{d20}$) rolled for damage (or healing) caused by a | |
95 | spell are modified by (up to) $\delta P$ in the caster's favour. | |
96 | Percentile dice are modified by (up to) $5\delta P$ in the caster's favour. | |
97 | This will \emph{not} increase a roll beyond the original bounds, but makes | |
98 | it more likely that the bounds will be reached. For example, a | |
99 | seventh-level Magic-user with $I = 16$ casts \emph{magic missile}; each of | |
100 | his missiles causes 4--7 points of damage, computed as $\min(7, \dice{1d6} | |
101 | + 3)$. Spells such as \emph{fire ball} have each die modified | |
102 | individually.\footnote{% | |
103 | The distribution this induces is slightly better shaped than the one you | |
104 | get by applying a modifier to the sum of the dice, but has the curious | |
105 | property of being non-monotonic. This is unlikely to be a problem in | |
106 | practice.} | |
107 | ||
108 | \item Saving throws against spells are penalized according to the caster's | |
109 | $\delta P$. Suppose our Magic-user casts \emph{fire ball}. A victim in | |
110 | the blast radius must save versus spells at $-2$ or take $\dice{7d6}$\,hp | |
111 | of damage, with each die modified upwards by two points. If the save is | |
112 | successful, half damage is taken, as usual. | |
113 | ||
114 | \end{enumerate} | |
115 | ||
116 | ||
117 | \section{Saving throw adjustments} | |
118 | ||
119 | Saving throws are modified by a character's ability scores. Which ability | |
120 | applies is dependent on the action the character takes to avoid the effect. | |
121 | Sometimes several abilities apply; then \emph{all} the modifiers are taken | |
122 | into consideration. | |
123 | \begin{itemize} | |
124 | ||
125 | \item Saves versus poison are usually modified by the character's | |
126 | Constitution. Similarly, saves versus paralysis (e.g., for a Ghoul's | |
127 | touch) are modified by $\delta C$. | |
128 | ||
129 | \item Saves against magical effects are usually modified by Wisdom. Not all | |
130 | saving throws against magical effects are Saves vs Spells: for example, the | |
131 | Save vs Turn-to-Stone for gazing at a Medusa is modified by $\delta W$. | |
132 | Similarly, the Save vs Death Ray for the \emph{finger of death} spell is | |
133 | modified by $\delta W$. | |
134 | ||
135 | \item Saves versus Dragon breath are usually modified by Dexterity. The Save | |
136 | vs Paralysis for being knocked over by a Dragon's tail is also modified by | |
137 | Dexterity. | |
138 | ||
139 | \end{itemize} | |
140 | ||
141 | ||
142 | \section{Weapons and combat} | |
143 | ||
144 | The weapon master rules in the \emph{Master} set are used. The following | |
145 | modifications are made to the system. | |
146 | ||
147 | \begin{tab}{mastery}{Mastery adjustments}{llMrMr} | |
148 | \th{Level} & \th{Abbr} & M & \delta M \\ \hlx{vhv} | |
149 | Unskilled & US & 0 & -2 \\ \hlx{+} | |
150 | Basic & BS & 1 & 0 \\ \hlx{+} | |
151 | Skilled & SK & 2 & +1 \\ \hlx{+} | |
152 | Expert & EX & 3 & +2 \\ \hlx{+} | |
153 | Master & MS & 4 & +3 \\ \hlx{+} | |
154 | Grand Master & GM & 5 & +4 \\ | |
155 | \end{tab} | |
156 | ||
157 | \begin{enumerate} | |
158 | ||
159 | \item Magic-users may use the dagger and staff, and thrown objects. | |
160 | ||
161 | \item All character classes may fight unarmed. Characters begin with Basic | |
162 | mastery at both Striking and Wrestling; this does not cost a mastery slot. | |
163 | ||
164 | \item Characters can acquire mastery in the (normal) shield, to improve the | |
165 | armour-class benefit it provides. All character classes who can use a | |
166 | shield are automatically considered to have Basic mastery in its use; this | |
167 | does not cost a mastery slot. | |
168 | ||
169 | \item Fighters and Mystics receive four mastery slots at level~1; other | |
170 | humans receive two slots. Demi-humans can use all weapons at Basic mastery | |
171 | at level~1, and receives no mastery slots. A level~1 character may | |
172 | \emph{not} spend two slots on the same weapon (to reach Skilled mastery or | |
173 | better). | |
174 | ||
175 | \item Fighters, Mystics, Dwarves and Halflings receive an additional mastery | |
176 | slot at level three, and again every third level after that (i.e., at | |
177 | level~3, 6, 9,~\dots). Clerics, Thieves and Elves receive an additional | |
178 | mastery slot at level four and again every fourth level after that. | |
179 | Magic-users receive additional an mastery slot at level five and again | |
180 | every fifth level after that. All characters gain an additional mastery | |
181 | slot every 200\,000\,XP after maximum level. | |
182 | ||
183 | \item The to-hit bonuses for weapon mastery are halved. | |
184 | ||
185 | \item The morning-star and flail (one- and two-handed) are added, as | |
186 | additional weapons for Clerics. | |
187 | ||
188 | \item Characters do not lose initiative automatically for using a two-handed | |
189 | weapon. Rather, a $-1$ penalty is applied to initiative rolls for using a | |
190 | `large' weapon; a $+1$ bonus applies for using a `small' weapon; see the | |
191 | weapons table for sizes. | |
192 | ||
193 | \item The bastard sword is designed to be used one- or two-handed. A | |
194 | character who acquires mastery in the use of the bastard sword learns how | |
195 | to use it \emph{both} one- and two-handed to best effect. A character with | |
196 | an empty off-hand can decide whether to wield the bastard sword one- or | |
197 | two-handed in each combat round with no penalty. An off-hand wearing a | |
198 | cestus still counts as empty for this purpose. | |
199 | ||
200 | \item A weapon can be used in a character's off-hand. To use a weapon in the | |
201 | off-hand effectively, one must learn how to use it to complement the main | |
202 | weapon -- it can't be learned in isolation. While one might acquire | |
203 | mastery of the normal sword, say, as a main weapon, one would have to | |
204 | acquire mastery in the use of a dagger as an off-hand weapon | |
205 | \emph{separately} with (say) the sword and the morning-star. A character | |
206 | Unskilled with an off-hand weapon strikes at a $-4$ penalty (and does half | |
207 | damage, as usual). | |
208 | ||
209 | \item One- and two-handed flails are different weapons, and a character must | |
210 | spend mastery slots on them separately. However, they are \emph{related} | |
211 | weapons -- see below. | |
212 | ||
213 | \item A character with a level of mastery $M$ with some weapon may attempt to | |
214 | use a \emph{related} weapon; the skills don't transfer completely, but | |
215 | related weapons (see table~\ref{tab:weap-related}) can be used with mastery | |
216 | level $\lfloor M/2 \rfloor$. | |
217 | This also applies to the use of a familiar off-hand weapon with a related | |
218 | main weapon. The use of a merely related off-hand weapon, even with a | |
219 | familiar main weapon, is always considered Unskilled. | |
220 | \begin{tab}{weap-related}{Related weapons}{ll} | |
221 | \th{Weapon} & \th{Related weapons} \\ \hlx{vhv} | |
222 | Bow, long & Bow, short \\ \hlx{+} | |
223 | Bow, short & Bow, long \\ \hlx{+} | |
224 | Crossbow, heavy & Crossbow, light \\ \hlx{+} | |
225 | Crossbow, light & Crossbow, heavy \\ \hlx{+} | |
226 | Flail, one-handed & Flail, two-handed, morning-star \\ \hlx{+} | |
227 | Flail, two-handed & Flail, one-handed \\ \hlx{+} | |
228 | Javelin & Spear \\ \hlx{+} | |
229 | Morning-star & Flail, one-handed \\ \hlx{+} | |
230 | Shield, horned & Shield, knife; shield, sword \\ \hlx{+} | |
231 | Shield, knife & Shield, horned; shield, sword \\ \hlx{+} | |
232 | Shield, sword & Shield, horned; shield, knife \\ \hlx{+} | |
233 | Spear & Javelin \\ \hlx{+} | |
234 | Sword, normal & Sword, short; sword, bastard \\ \hlx{+} | |
235 | Sword, short & Sword, normal \\ \hlx{+} | |
236 | Sword, bastard & Sword, normal; sword, two-handed \\ \hlx{+} | |
237 | Sword, two-handed & Sword, bastard \\ | |
238 | \end{tab} | |
239 | ||
240 | Note that the property of being related weapons is \emph{not} transitive! | |
241 | ||
242 | \item The \emph{deflect} ability makes high-level characters nearly | |
243 | untouchable, as many have noted. The new definition allows an attack to be | |
244 | deflected if $\dice{1d20} + \delta D + M$ is greater than the attacker's | |
245 | (adjusted) hit roll. Deflection does not work against device-hurled | |
246 | missiles; it does work against thrown weapons. | |
247 | ||
248 | \end{enumerate} | |
249 | ||
250 | ||
251 | \section{Alignment} | |
252 | ||
253 | The idea of alignment as an observable property of the game world is absurd. | |
254 | Alignment languages and the Cleric \emph{know alignment} spell are | |
255 | abolished. | |
256 | ||
257 | ||
258 | \section{Clerics} | |
259 | ||
260 | \begin{enumerate} | |
261 | ||
262 | \item Clerics who can Turn Undead creatures (with a `T' or `D' result) can | |
263 | optionally control them instead, as an Avenger. This is considered to be | |
264 | an evil act. | |
265 | ||
266 | \item The spell \emph{know alignment} is replaced by the AD\&D spell | |
267 | \emph{slow poison} as follows. | |
268 | ||
269 | \textbf{Slow poison} \\ | |
270 | Range: touch \\ | |
271 | Duration: $L$ hours \\ | |
272 | Effect: Slows poison in the body of a creature \\[\medskipamount] | |
273 | Slows the effects of poison on an individual. A creature can be affected | |
274 | even if supposedly killed by poison, in the previous $L$~turns. The poison | |
275 | will remove one hit point per turn (though never reaching zero while the | |
276 | spell lasts). | |
277 | ||
278 | \item Druids must still be Neutral. Maybe I'll relax this later. | |
279 | ||
280 | \item Clerics (and Druids) of level 9 or higher don't need to choose their | |
281 | first-level spells in advance each day; they may cast any combination of | |
282 | first-level spells up to the daily maximum. At level~14, second level | |
283 | spells no longer need to be chosen in advance; similarly for third-level | |
284 | spells at level~18, fourth-level at~23, fifth-level at~27, sixth at~32 and | |
285 | seventh at~36. | |
286 | ||
287 | \end{enumerate} | |
288 | ||
289 | ||
290 | \section{Magic-users} | |
291 | ||
292 | \paragraph{Background notes on spell books} | |
293 | A standard spell book is an enormous thing. My \emph{Dictionary of the | |
294 | English Language} (Johnson) weighs about 5\,kg. \emph{Unearthed Arcana} | |
295 | suggests 450\,cn; \emph{Sage Advice} (Dragon \#134) suggests 400\,cn -- | |
296 | backpack size. This doesn't seem too far off. \emph{UA} also suggests that | |
297 | a standard book cost about 1000\,gp, which may be reasonable. I don't | |
298 | propose to apply the limits on capacity of spell books. | |
299 | ||
300 | \emph{UA} also suggests travelling spell books, which are smaller somewhat | |
301 | cheaper but with less capacity. As stated above, I don't want a capacity | |
302 | limit on standard books (the things are huge already!) but limiting | |
303 | travelling books seems reasonable. | |
304 | ||
305 | \begin{enumerate} | |
306 | ||
307 | \item A standard spell book costs 1000\,gp, measures $15'' \times 9'' \times | |
308 | 3''$ and has encumbrance of 350\,cn (due largely to bulk). There isn't a | |
309 | practical limit on the number of spells it can store. | |
310 | ||
311 | \item A travelling book costs 500\,gp, measures $9'' \times 6'' \times 1''$, | |
312 | and has encumbrance 60\,cn. It can store ten spells; level is irrelevant. | |
313 | ||
314 | \end{enumerate} | |
315 | ||
316 | ||
317 | \section{Fighters} | |
318 | ||
319 | \begin{enumerate} | |
320 | ||
321 | \item Any Fighter may become a Paladin or Avenger, regardless of alignment, | |
322 | if the appropriate religious hierarchies accept him/her. | |
323 | ||
324 | \end{enumerate} | |
325 | ||
326 | \paragraph{For consideration} | |
327 | Maybe it makes sense to allow neutral Fighters to become Druid-like -- giving | |
328 | up the ability to Turn Undead for Druid spells along with the Cleric spells | |
329 | already obtained for sufficiently high Wisdom. | |
330 | ||
331 | ||
332 | \section{Thieves} | |
333 | ||
334 | \begin{enumerate} | |
335 | ||
336 | \item Die rolls for the Thief abilities Open Locks, Remove Traps, Move | |
337 | Silently, Hide in Shadows and Pick Pockets are adjusted by the $5 \delta | |
338 | D$. | |
339 | ||
340 | \item Climb walls is affected by $\delta D$ (not $5 \delta D$). | |
341 | ||
342 | \item Find Traps is affected by $5 \delta W$, as described below. | |
343 | ||
344 | \end{enumerate} | |
345 | ||
346 | ||
347 | \section{Searching} | |
348 | ||
349 | \begin{enumerate} | |
350 | ||
351 | \item Rolls on $\dice{1d6}$ for searches (e.g., for secret doors) are | |
352 | modified by $\epsilon W$. | |
353 | ||
354 | \item Rolls on $\dice{1d20}$ for searches are modified by $\delta W$. | |
355 | ||
356 | \item Rolls on $\dice{1d\%}$ for searches (e.g., for traps) are modified by | |
357 | $5 \delta W$. | |
358 | ||
359 | \end{enumerate} | |
360 | ||
361 | ||
362 | \section{Bugs found/fixed} | |
363 | ||
364 | \begin{enumerate} | |
365 | ||
366 | \item The rules for evasion in the wilderness are obviously wrong: more | |
367 | pursuers should have a better chance of catching a party than fewer. I've | |
368 | attempted to fix the tables but I'm not completely thrilled with the | |
369 | result. The AD\&D rules seem wrong too, so they're no help. | |
370 | ||
371 | \end{enumerate} | |
372 | ||
