It is a tiny area. Just a little pool--they can barely move at all.
Not quite true. Pool dimensions given are
minimums. They could be larger. I easily envision an earth weird pool taking up a large underground cavern. Combine that with summoned earth elementals moving in and out of the walls and ceilings, and I see little tactical disadvantage.
jody: Yes, they do seem more like plot generators than combat encounters. But like other elementals they can be bound into service and would of course defend themselves. I've learned to never underestimate a PC's ability to pick a fight with the wrong creature... like the NPC from whom they are 'supposed' to recieve the next plot hook.
I'd probably run an encounter like that anyway, with most spells limited to divinations, enchantments, and protective spells. The stats just seemed off and I was hoping there was some obscure rule or tactical insight someone might have picked up about them from actual play experience.
But then as they are bound to their pools yet have both regular movement and fly, swim, or burrow speeds and have regeneration but no listed weaknesses to attack types from which they take normal damage, have a very high caster level for their CR, and are in the MM2, they could just be messed up.
