Brother Balatin despawned after 6 minutes
 

Brother Balatin in dreadlands (http://wiki.project1999.com/Brother_Balatin), spawned after a couple of hours of PH killings.

He has stayed up for 6(ish) minutes (the normal "repop" time), than despwaned.

6(ish) minutes after, a new PH popped.

Checking in-game friends and some source (http://eqthieves.com/class-monk-epic10.htm
"He has a Plaguebone Skeleton as a place holder and the respawn is approximately 6 minutes. Brother Balatin despawns after approximately 30 mins. ")
it should be 30 minutes before depop.

I think once you agro him he becomes 6 min, but if you let him sit he stays up for 30. Pro tip though, he doesn't despawn while agro'd so I kited him around while I was waiting on a chanter and the person with a pipe.

It was 30 min last patch, so it would have had to change recently.

Bah ... This.
Ofc, being there with a monk didn't think about that. I just FD'ed him out as he popped.

Yeah ... Figured out by myself. I was enough lucky to have him repopped after just one PH and kept aggroed till everyone was there.
