So, for one reason or another, I want to make an illusionist in a Pathfinder homebrew-setting campaign. For certain reasons having to do with the stigma against magic, wizards are all but unavailable. I've pretty much come down to a Wayang Witch with the Shadow Patron or a gnome sorceror with the Umbral bloodline.
I'm leaning towards the witch, using stealth and conjuration/illusion to do battlefield control, with my hexes for buffs and debuffs. The sorceror, however, might be more mechanically effective.
Does anyone have any experience with either of these builds? Would the witch be playable?
