Seeing the centipede is near the exit grate in this room, Tanith decides it needs to be dealt with. Not wanting to blow her cover, she begins chanting some incantations and the sounds of many feet can be slightly heard.
[sblock=ooc]Tanith begins to cast Summon Monster II since it won't negate her invisibility. She is going to summon a Fiendish monstrous centipede, Large. Casting it so it appears right next to the other one.
