Arcanist

Arcanists are a hybrid class of Pathfinder which merges the magical powers of both Sorcerer and Wizard to force the laws of nature on the table and forcibly violate them while they're screaming. Moreso than plain Wizards, at least. In a way, they're a variant of Wizards, with the need to memorize spells each day, but they can use a spell multiple times a day since the spell only eats up a slot. On top of that, they also have a Reservoir of innate energy they can use to empower their spells by boosting their DC/Casting Level or for their unique feature: Exploits. See, these either act like spells (like shooting acid out of their palms, making yet another magical shield, or temporarily enchanting weapons) or claim specific aspects of their parent classes (like Sorcerer Bloodline Powers, Metamagic, Wizard Schools, and the like); at level 11 and beyond, you can then select bigger Exploits which boost the Exploits picked earlier, like hijacking spells from baddies on the Arcanist's level or redirecting the directions of certain spells (or absorbing their effects).

Archetypes further cross them into other classes, like the Arcane Adept, which taps into the abilities of the Magus like a Bladebound, the Occultist, which does summoning, or the Blood Arcanist, which gives the Arcanist a full Bloodline to gain powers from in exchange for a few Exploits.
