I recently was gifted a Merfolk boon for PFS! EEEEE! I want to theme the character around light and darkness (how water affects light is one of the things I find cool about the ocean). I want it to be a caster for sure, but otherwise I'm not sure how I want to go about it.
An initial idea would be some kind of shadow caster, but from what I've read about them, they feel very feast or famine in addition to practically mandating Wayang shadow stuff and non-PFS material.
Thoughts?
