Vampiric cloak gives life steal

Yesterday I did 1 hour Pumpkin instance (I will post small hunting log soon), but today I realized that there is a way to loot Vampiric cloak that gives lifesteal inside Pumpkin instance. The formula for the success seems to be like this.

1.Loot Evil essence in the pumpkin instance.

2.Take it to some coffin in there.

3.Then spawn boss mob named Count Vamp of Boorum.

4.Kill vampire and you got a cloak.

Aperantly if you wear that cloak you get 1% life steal. Meaning if you do 100 HP damage you will be healed with 1 HP.

The cloak at the moment look like this, but the look will be changed later.
