Of course it seems like Wizard with an Illusion school speciality is the way to go, but with the upcoming Remaster changes removing those schools I thought I’d ask you find folks.
Plus I’ve only been playing since Feb. 2023 so I don’t really know the classes all that well. Perhaps there’s a ‘hidden gem’ in there I’m unaware would make an excellent Illusionist.
EDIT: I’ve checked AoN and it seems that the Occult tradition gets all of the Illusion school spells, plus a few more that Arcane does not!
Even though they’re getting rid of spell schools in the “traditional” sense, they’re replacing them with literal schools or colleges. Surely there would be a college of illusion somewhere in Golarion that you could’ve attended.
The core rulebook has an illusionist sample wizard on page 212. If you’re playing free archetype, you could maybe combine it with the Captivator archetype for occult spell fun.
As stated this is for PFS (Pathfinder Society) and as such no free archetype is available.
So far I’ve found that Sorcerer (Djinni) is a pretty good fit for illusions.
