You are gifted with the ability to defeat the powers of healing.
Prerequisite: Channel Negative Energy class feature, ability to cast bestow curse.
Benefit: Damage dealt by you is cursed. It can only be healed naturally with a successful Fortitude save (10+1/2 your character level+ your Wisdom or Charisma modifier [whichever is higher]). Magical healing requires a caster level check (DC 11+your caster level) or remove curse. The curse is broken once any portion of the damage dealt has been healed and the victim is immune to your curse for 24 hours.
