As my current campaign is slowly moving towards its end, I have started looking ahead to what I may play next. I haven't played a full caster in a long time so I'm strongly considering that route. I don't like it when my spells fail so I've been looking at ways to get my spell DCs way up.
I put together an enchanter build. A Kitsune Fey-blooded enchanter can get an extra +7 to compulsion spell DCs by level 16. That's huge!
I would much prefer to focus on transmutation or necromancy spells, but I can't find anyway to really bump those school spells DCs up. I don't like specializing in enchantment or illusion since so many creatures are immune to them.
Aside from the obvious Spell Focus feats, or going Arcanist for Potent Magic (all of which can be applied to any school), are there any good tricks out there for boosting specific school DCs?
