Well i don't think 25% (not growing!) insanity helps much against the dominance of the tartarians in late game.

Isn't it possible to stop healing the undeads via chalice and gift of health? This would hurt them and its also thematic.
I can't believe the chalice was created to mainly heal undead afflictions!

I would also modify gift of reason. You could split the spell into different spells which effect only one (or 2) size category. So GoR a human (size 2) could cost 10-20 gems and a size 6 unit cost more like 30-60.
