So, I'm considering the following House Rule with regards to psychic abilities:
If you get a natural 20, or beat the DC by 10 or more, you don't take ability damage or lose sanity.
I'm consider something similar for spells, probably a spellcraft check(to give the skill more usefulness), with the same rules, and the DC based on the range of the spell. Self: DC 15, 30ft DC 20, etc. And I think it makes sense, as the higher level you are, the more power you're messing with, hence range increases as does the DC.
Thoughts and Feedback?
