Cavemen have a lot of experience traversing tight spaces in caves, and thus are always able to squeeze through a diagonal space (except possibly in Sokoban).
Alternatively, they are able to squeeze through diagonal spaces while carrying much more weight than other roles.
Cavemen receive a spellbook of fireball as their crowning gift, which they can always cast with 100% success rate. Flavor-wise, this ties into “discovering fire”.
Livelog when a Caveperson player creates fire for the first time.
Cavepeople can safely sacrifice same-race monsters to “give them to the ancestors”, but only if the monster wasn’t killed by the player.
Buff Cavepeople by giving them a direct boost to carrying capacity beyond what they get from their Str and Con, to the point that they can carry more weight than any other role.
Cavemen wielding clubs get damage bonuses that increase with their skill in club, to make up for clubs’ awful damage.
Replace Cavemen’s quest artifact with scales from the Chromatic Dragon (their quest then becomes “kill the dragon that is terrorizing our people” instead of “fetch the artifact from the dragon who stole it”). The scales only drop when she is killed, rather than her being generated with them (thus, they can’t be stolen). The scales could either be implemented simply as a base item akin to chromatic scales in UnNetHack which provide a cocktail of resistances, or as an artifact. If implemented as a non-artifact, the Caveman role will have no associated quest artifact.
The scales should NOT be enchantable into scale mail. The pile of resistances is good enough.
Don’t gift a character a spellbook as a prayer boon if the character is illiterate or certain roles (like cavemen or barbarians), and if a spellbook is given limit its level somehow so that a character doesn’t get a spellbook of much too high level.
Blowguns, a weapon which can be used as a launcher for darts. (Cavemen can thematically use these.)
Barbarians and cavemen get weapons/ammo instead of spellbooks as a prayer boon, or enhancements to their current weapons.
Cavemen (maybe only lawfuls) get a small alignment bonus for cannibalism, because it is honoring the ancestors.
Cavemen get a small alignment penalty for writing or using complex tools.
If you are a Caveman, you get telepathy or clairvoyance while you are hallucinating.
Cavemen get a large damage/to-hit bonus when throwing spears at large mammals, or an alignment bonus for killing large mammals with spears.
The Caveman pantheon should be changed to monosyllabic god names like the rest of the Caveman-specific text.
Cavemen get a berserking bonus if their pet gets killed.
Some roles get food appraisal as a permanent intrinsic. Caveman at level 6, Tourist at level 10, maybe Healers at level 1 but they already get poison resistance so maybe not.
