Cyrik Skylark said:Our battle plan, as it stands now, is like this:
1) Clerics Greater Planar Ally with their 8th level spells, bringing in two planetars each
2) Clerics Gate in a solar each - although if anyone has any good ideas for other creatures to gate in, I'd appreciate it - 34 HD is our limit.
3) Wizard leads off the fight with a Mord's Disjunction, hopefully taking down his buffs. Meanwhile, he's got Shapechange cast, and in a pinch will shift into a beholder and fix the antimagic ray on the psion.
4) Everyone else pulls out the big guns.
So, any advice?
