Races
Where do I place the number of arms/legs/heads/etc in the races file in TOME 3?
TheFalcon: Well, it looks from the entries that you use a body = {} value, and in the array you can put the same kind of things as in the monster body definitions. (see /data/monsters/races.lua).
OutoLumo Can I make race have a variable number of say arms? Ents with 3-5 arms would be cool 
(Then again, what would that require from the wielding arms checks? One could use a two-handed weapons AND a shield AND cast spells at the same time? How about spells that couldn't be cast without a third arm?)
DarkGod: You can do all you want, although, whats the point of random boby parts ??? people will just birth-scum the max
Orvin: Could be interesting for Ents to be able to chose at birth between three body options: many branches and few roots (+1 arm/hand-type slot, -1 leg/foot-type slot), equal branches and roots, few branches and many roots (-1 arm/hand, +1 leg/foot).
