Infernal killing every undead on spawn.

[Vudaris]

There is an Infernal who is killing everyone who comes out of the crypt @ Shadow glades. Please do something about it.

He got me too .... just release go to your corpse res , die do that again and u should be fine.

It was likely brought there by a Warlock, the best thing you could do is wait. If it continues for several hours that is usually when the staff might get involved.

Its have a cooldown of 1 hour , and he will stay there for a while. It take like 30 sec and its done.... to complain to a gm about that and to open a ticket its really crying for nothing.

"Prior to Patch 3.0.2, the length of time for summoned Infernal was 5 minutes; after this time, the Infernal would become hostile and had to be re-enslaved."

Also a quote from Wowhead

I miss dropping this guy in low level towns and watching him obliterate everything and everyone

Basically...welcome to vanilla.
