Deathpunch? Soul Sap? Elemental Absorption? Vampiric Touch? Horrific Scream?
Witchcraft has a lot of very good spells.
A magic school should never scale off anything but Int.
Right, I know people are opposed to this for lore purposes, but gameplay-wise I think it would fix a lot of stuff. It personally wouldn't bother me much. I've played rpg systems in which magic can be based off of everything from charisma to dexterity to constitution, depending on the spell. A lot of fantasy has magic be based, at least partially, on physical attributes.
