Sorry for the absent weekend; I should be able to post at least once from now on, during the weekends.
Voadam, I did give Terrek a chance to detect the rats on the other side of the door, but he failed. I forgot to include that in the ooc descript at the end, sorry. It's not certain he would, in part, because this whole area smells of rat. Scenting more rats on the other side of barriers like doors is certainly possible--but by no means certain.
Shayuri, Voadam has it right. You can 5-foot-step further in to the west, or retreat to the east, and give someone else access to attack the rats. I will have you step further in, as I think that's more IC. : ) Note that anyone who moves more than 5' to take Kuma's place will suffer AoO's from the flanking rats--but for those AoO's the rats will not be flanking, and the char will have a +4 AC due to cover from the doorway.
Now for the battlepost.
