Came over last night to do this part of my epic. We had to wait about 90 minutes for them to spawn. I have no idea when they were killed last. Could have been last night and a 24 hour wait or could have been a little before we got there and a 2 hour wait.
I wandered around the room. Zoned in and out a few times. Made sure invis was was off when I zoned in. I had my bag and crystals with me, crystals were in the bag.
A friend who did this part said they had to wait too and the room repopped several times although I heard they did not wait as long as we did.
I'm not sure exactly, but guessing by the other timers on the epic line, I'd say 24 hours, I tried to spawn them 2 hours after another druid killed them, and they didnt spawn. Also had a group (we were totaly unprepaired) with me and we wiped taken Glenfire down, roughly 10-15 mins later Azibelle despawned, and didn't respawn, gonna try again tommorrow.
same they have to be at least lvl 73 but dont let thheir lvl fool you they are not hard at all to kill max hit is under 1k and dont have that many hps.
I soloed this as a lvl 70 druid. YEs it is possible. The first attempt with my group actually failed due to chanter dying on spawn. After we died, the group had to disband, so i figured I would mess around with the spawns, to see what I can do. All the adds popped back in the room. Adds DO NOT assist in the room while u pull named. I pulled named, ran him all the way to zone in (NON SNARED) then zoned.. Came back in the zone and finished him off. Did the same thing with the other named. They dont have very much hp. Easier then the mobs at the zone in. They con red to me 70.
