Our group just got done playing through this, and my fighter now has a permanent hatred of all things Thassilonian (although she did get to use her lovely mage-killing feats). I enjoyed the scenario a lot; the threat of imminent death makes it much easier for my ADD brain to pay attention!
One funny moment; Krune (may he rot in the lowest hells...) summoned an azata and gave it the command to kill my fighter/bloodrager, since I was the most immediate threat. Then he does his little 'teleport around the mausoleum' trick. Well, I activated my Boots of Speed to grant me haste, and took off down the hallway with my 140-ft-per-double-move speed to hunt the bastard down. The azata followed, having to double-move to keep up.
The azata and I then played 'follow-the-leader' for the next several rounds as Krune teleports all over the damn building to get away from me. After the second round, the azata stopped apologizing for being forced to attack me, since it couldn't, because of the speed I was using, and we had a running (pun intended) conversation about these @*&%^$* mages and how there really ought to be an easier way to fix this problem...
