Vampire feeding and an Idea for bolt escape counter

Thevampirenight

I had this idea for bolt escape instead of instant cast it activates 2 or 3 seconds later and during time vampires can feed stoping the bolt escape and the cooldown happens only when enemy players are nearby or in combat that and when an humanoid enemies is below 25 percent and you have not used the drain you can feed off them. They could block it on bosses but allow you to sneak up before combat and feed on humaniod bosses
