We had a plan for East Dire Maul to get the key: In the front door, engage Pusillin (he runs off), exit and return via the second entrance and fight our way to where Pusillin ends up. We had no idea if that was a workable plan, but it was a plan.
The first thing, getting Pusillin off and running, worked great. We ran around to the second entrance and started clearing for our fight down the hall. I noticed an imp in the other direction who looked just like Pusillin, it was Pusillin. Apparently, he only runs part way. We killed a few trees in that direction and were able to get him running again.
We fought our way down the hall with little trouble. The biggest danger is the single walkers showing up in the middle of a fight. We were lucky, and vigilant, and made it to the end in one piece. There was Pusillin again, he needed another push.
We had looked into, but never fought in the three chambered “Pusillin room,” for the lack of a better name. No longer were we fighting trees but two legged guys with tails. Some of them were Rogue-like in that they could fade in and out. One more talk with Pusillin and he ran up a ramp saying only, “Die!”
We had three guys down stairs to clear first. We took out two of them before dieing, as Pusillin suggested; the return fight was easy with just one remaining. Now a slow creep up the ramp, the only thing up there was Pusillin.
We expected a fight when finally challenging Pusillin. We expected he’d call friends. I, the Warrior, activated him while the Mage, and Priest, stood back. Unfortunately, when the friends came, they came up the ramp behind. Pusillin grew in size and was now an aggressive 57 caster. We died again.
Unlike some quests fellows, Pusillin and friends remained on our return. We were able to pull the friends downstairs to take them and then dispatch Pusillin. We all looted a key. It was an impressive victory.
We tried our key on North Dire Maul, it worked. I’ve read where Rogues and Hunters solo this quest, although Rogues don’t necessarily need a key.
