None of the primary stats (burliness, sagacity, nimbleness, cadishness, savvy and nimbleness) from skills are added to your character. For example, make a new character on Going Rogue/Permadeath/RealmOfDiggle with: Swords/Axes/Maces/DualWielding/Shiel/Berserker and Killer Vegan. Your burliness will be 14 instead of 15 and you health will be 36 instead of 37. The +1 burliness from Killer Vegan is not counted. This remains true even when you level up; these stats are never added to your character.
Forgo to specify this is with path 1.1.1 and the wizards land expansion installed. Can anyone else confirm the bug?
