Corrupting Smite

Pulling from their will, this spell allows a caster to imbue their melee strikes with hatred for Evil. Once cast, a portion of the soul of the caster will have a chance at being corrupted, to power the spell.

The user can add 3d10 force damage to attack roll damage against Evil aligned beings. On a critical hit the damage is 3d12, and will not be doubled.

Once the spell ends, the user will have to make a Wisdom saving throw, DC of their spell casting modifier. If the user fails the saving throw, than corruption can take begin to take hold. After 5 failed saves, the caster's soul has become corrupted, and their alignment will become some form that has Evil in it.
