More occultism, and time for even more spells!

Occult Master Variable actions Feat 15

General Skill
Prerequisites legendary in Occultism

---

You force the spirits to do your bidding. Once per day, you can choose an occult 2nd level spell that is not uncommmon and attempt a DC30 Occultism check. If you succeed, you cast the spell using as many actions as that spell normally takes. You use either your Charisma or Intelligence as the spell casting ability and are considered an expert to determine spell casting attack or save DC.
