The PC's tore through the doppleganger's hideout fairly quickly. The Invisible Stalker room presented the most difficult challenge. The PC's had never encountered Invisible Stalkers before and certainly weren't expecting them in a doppleganger hideout! The resulting combat lasted nearly an hour as the PC's were knocked around by the stalkers, before finally whittling them down and killing them. Telakin proved to be a semi anti-climactic encounter, though he did manage to down one of the PC's before getting blinded and thoroughly trashed.
I modified the mind flayer's hideout a bit, swapping out the octopins for illithidae and the drow from grimlocks. I also added some phycomids and dusanu to the fungal room. There are, at any time, 5 to 6 PC's in the group so I figured I'd up the challenges a bit. I also replaced the drow cleric with an ogre mage fighter. The vrock got swapped out for a brain golem and the spirit naga I replaced with 5 advanced runehounds. Zyrxog got restatted with an extra level of Psion, so he can manifest some pretty devastating powers, but he doesn't have the hp or longevity of the original Zyrxog.
The PC's tore through the fungal room then they nearly died when the three grimlock barbarians hiding on the ledge ambushed them. One hung back and tossed alchemist's fire at random characters, while the two fighters in the party climbed up and got the crap kicked out of them. By the end of the fight, the two fighters were in the negatives and the party wizard had been lit on fire.
The runehounds went down quickly. Only one vile spew attack actually hit a party member, the others all missed, though they did deal some impressive damage before dying. The runehounds had neither the hp nor the AC to stand toe-to-toe with the two greataxe and glaive-wielding fighters.
