I'm the player behind the sole surviving Wizard from our encounter with the 3 brain-suckers.
I did try to separate them with an ice-wall, but they simply dimension door'd through it, engaged one of the fighters, then two of them came at my me. I dimension door'd away after they got a tentacle on my character, and should have just retired from combat right then. I stayed around for several more rounds before we the rest of the party started falling. Then I ran away and rope-tricked out of sight.
"It was horrible! <SOB> All the screaming and slurping sounds. The squid-faces even burped after they'd finished the druid off. I hope they get indegestion!"
I was thinking that a "Dimensional Anchor" followed by a well placed "Black Tentacles" might help us slow them down and allow the party to take them one at a time. Just wish I'd had those prepared. As it played, "Rope Trick" was Nyneve's last party favor and she barely made it out with her grey matter intact (oh wait, they threatened to make her a thrall - that would have been fun).
Protection from evil seems like it will help with a +2 on saves, even a standard globe of invulnerability should stop the mind blast (as its a 4th level SP). Although I wouldn't want to be caught in a stationary 10 foot sphere while the squid-faces run right in and eat my face.
Is it just me or are Psionics a bit ...erm... broken. Power Penetration gives a +4 to your checks but Spell Penetration is only a +2. Burn a feat and take Power Resistance and get Spell Resistence for free! Impossible to get Spell Resistence in the standard rules that easily. Everybody'd be doing it!
