Immersa hits with one claw, but does not damage PU2.
Round 173: PU2 concentrates, Immersa misses with her AoO (rolled 12), and they are both surrounded by a cloud of swirling, abrasive dust. Immersa does not quite avoid any of the flying grit, taking 11 points of damage. Immersa is at -2 HP and dying. PU2 dodges some of the grit, taking 5 points of damage. PU2 has 15 HP left. PU2 moves out of the cloud to 115N55E. Observers from the Lawful Good side of the arena see PU move north from 10N65E to 40N65E, behind the cloud. The two clouds are 20' radius each, 20' high, one centered at 35N40E, and the other centered at 110N75E (it abuts the north wall).
OOC A valiant effort, Immersa, but as mephits like to say, "It's better to be lucky than good."
First up in round 174 for Lawful Good is a ramadeen (Miniatures Handbook). I have E-mailed you the ramadeen in case you do not have the required book.
