All spell DCs are, for Cleric, FvS, and Druid. But I've added this note to the OP:
"This is also just focused on spells. There are various other abilities with DCs that are based off of attributes other than Wisdom; these are beyond the scope of this post."
OK. Not criticizing such a character at all, but it's a very different sort of character than a DC-based caster, which is more what I'm focusing on in this thread.
