Alchemy: Create Golem, SP: Gravity Inversion, and Alchemy: Mana Pistol
I think Evie is very versatile. Just really frail though.
Golem is tricky, Gravity Inversion is WAY later if I remember correctly, and you still use your skills as hotkeys inplace of items, so really you get super limited there.
@Fracture, you realize extra weapons would do literally, NOTHING for you. You gain no change, evie could switch between things, but every other class gets nearly NOTHING in that exchange.
