6-level Necromancy
This spell scrambles a target's mind. The target must make an Intelligence saving throw, or take 5d12 psychic damage, and become incapacitated for the duration of the spell. Targets also become affected by confusion; re-roll if you get a 6. Up to 10 creatures may be effected at a time. Casting on an 11th target snaps the 1st target back to reality. Undead and constructs are immune to this spell.
