The timer doesnt stop, or change you just lose the buff until he zone shouts again.
The training part works awesome, have a shammy, soulstoned priest, or hunter / rogue with cables that can shed aggro or snake down there. Die in the gated room, it wont close til you engage a fatty.
I am of the opinion that the Human warlocks and their pets are meant to be avoided. They are higher levels than the damn magistrate (61).I think if you concentrate on the group of ghouls you can zigzag around the zone. I have yet to test this theory.
Some points of interest.
Maleki ice blocks people (I dont ever remember him doing this before)
Ramstien stuns whoever is on top of this hate list and moves to someone else)
After Rammy dies the skeletons try and fake you out, first a few come, then seconds later the zerg comes out of the tunnel.
We easily dispatched the baron with 2 Warriors, Priest, Mage, Shaman. Disproving my theory that the Baron himself got a buff. If youre with a mage dont waste your mana on your area effects of any kind, the mage should handle the skellies alone, it takes two casts of IAE to take them out. All DPS should be on the baron, the faster he dies the less waves he spawns.
