Thorden is going to take 20 to search the two buildings in detail, since we have time. His thoughts are mainly turned towards anything that looks off-such as arcane markings, burns in the floor, walls, or ceilings (thinking on the brimstone smell), anything that one probably wouldn't find on a farm-plot.
I can still use two of those entangling blasts, which cuts his damage in half but should hold them for a sec. He can also do the Earthen Grasp, which would grapple one of them, or both in two turns. I'm pretty sure that could interfere with a teleport SLA (correct me if sla's work that much differently than spells), and it would at the very least screw up their glaive-useage. If I can boost the thing's strength high enough to pin them, the -4 to AC would be swell. At the very least, they'd lose their dex to AC. If pinning them to the ground to somehow make them prone (I dunno shit about grapple, other than it's a crap shoot) is an option, the extra nick to AC would make Thorden and/or Grizz going to town on them that much more appealing. Power attack to our hearts desire, see how much HP these fuckers have.
Of course, that's hoping my giant immobile rock-hand can make the touch attack, and then not screw over the grapple check. After that, I'm kinda reduced to more rock-hurling, or hitting them with a flail, which would be nice
