Necromancer’s enervation spell has been exchanged for reap, which recovers HP based on damage dealt.
Reap The reap spell uses a polearm to attack a group of enemies with abyssal, life-draining magic. The attack first hits victims that are actively attacking the caster or the caster's party and then any uninvolved nearby targets within range. About half of the damage dealt per victim is recovered up to a max of 50 hit points per hit. Syntax: cast 'reap' <target>
