A few zero effort changes to add variety...

Well damn, you're right, half elves had nothing similar to humans. I guess the only thing I saw similarly between them was Favored Class - Any.

Half elves got the shaft in 3rd Ed... But enough there, I like the stats you've got there. Elf and Dwarf would both seem reasonable to add, but orc would probably be too similar to Minotaur, stat-wise. Halflings might be like Elves but with Vitality and Willpower evened back out. Maybe give the little buggers some sort of bonus to Evasion as a racial trait, somewhere in the 5-10 range? Whatever would balance with the Insectoid Natural Armor.

Id like to see a greater variety of the existing spell ingredients placed in the levels. I was always reluctant to make and use speed and rage (sulphurous) potions because of limited ingredients and their relatively short lived bonus effects.

More evidence of past (failed) prisoner parties would be great too... Toorum can't be the only one who kept a journal.
