Seanon is still to busy defending himself from the tiny spiders (nauseated), but the verming mass is slowly torn apart by sonic damage from wepons and acid damage from armor. when elkal shoots flame at it, hundreds are burned down and the huge swarm starts to dissipate, still crawling arround to move out of your way but no longer attacking you like a coordinated mass.

Your followers turn their attention to the newlly arived spiders to take them down, but some of them are still getting spider off their skin (nauseated).
