My favorite curse for my favorite enemy.

Prerequisites: Hexblade Curse, One Mental Attribute 21+

Benefit: When using your curse ability, you can choose one of your banes known and apply it to the target of the curse. The target is also affected by that bane spell as if it were a single target spell. The will save against the curse is used to determine if the bane takes effect. You do not need to sacrifice a spell slot to do so and cannot enhance the spell by metamagic.
