Ok. I thought of a way to standardise the Domains.

All Domains must give one of the following:
Code:
#1: A free Occult Power only available via this Domain.

#2: An X per day Su ability, plus a +1 to +2 bonus to one skills

#3: 1-2 Bonus Class Skills, A skil Trick and a +2 or +6 bonus to one or more skills.
What does anyone reading this think?
