Given I hunted the bear a number of times on Live, this doesn't seem right. However, here's what I always did:
1. Sit in the tunnel you enter the maze from (after you swim) as far away from the corridor that mobs wander through as possible - max casting distance.
2. If you see an IBS wander by, cast a DoT on it and kill. You now have 6.5 or 7.5 (don't remember) hours til the Bear spawns
3. If you see a Lich wander by, don't cast on it, it'll kill you
[You must be logged in to view images. Log in or Register.]
Don't enter the halls of the maze, you don't need to and you'll likely die from the Lich or some other mob (I did go in once and I got nuked by something other than the Lich (a wizzie?) and had to get a drag out by a high level guildy)
I did this about 5 times on Live for myself and guildies and never had any problems aggroing the Lich, so it's aggro radius here must be way different than Live...
