Some kind of Bishop revamp

Perfect Heal: Buffs the effectiveness of Heal to have 600% Healing Power and deal 3 hits of 250% damage to undead enemies. Holy elemental. Also allows Heal to over-heal party members by 10% of the caster's attack range (capped at 10,000 health). Over-healed party members have a bright purple health bar and deal take 15% less damage. The Bishop cannot over-heal himself.

Fix'd. I like that it sounds similar to TF2 Medic mechanics. And I'm assuming this is a passive skill?
