Angel: 25 faith for 75 CP
Would be really OP with Glowing Guardian and Dracul while simultaneously being almost useless for Binlor, Taurog, and Tikki Tooki. Enlightenment in particular would be totally broken for an Angel, which could (very easily) have it by level 1.
Minotaur: Covers up 10% of dungeon for 100 CP
I'd make it a pre-set number of tiles rather than percentage based. No reason to penalize a race on smaller dungeons. Biggest problem I see is the randomness of this one, and the fact that it would be very stupid to convert anything before the map is completely uncovered.
