See IC for Paxre's death and monologue.

R15T19: Rat swarm will tear open Paxre, but otherwise is no longer a functional part of this battle ...

R15T9.9: Muhrbala screehes and hisses, and then hovers at full defense.

R15T9.7: Wererat closes (non-flanker) and misses.

End Round 15, Begin Round 16 ...
R16T27: Girrigz misses.
R16T20.5: Flanker misses.
R16T9.9: Murray has disappeared, but then pops right back into view as he stings the flanker in the chest for 6 mod, and he falls unconscious in the muck.
R16T9.7: The non-flanker steps into his fallen friend's place.

R17T27: Girrigz stabs the now-exposed pseudodragon for 28, 3 bleed, and bewilders him so that he suffers a -2 AC against Girrigz' attacks.
R17T9.9: Murray tries to use judicious amounts of stinger venom to staunch his own bleeding, which provokes an AOO from both flankers (miss). He is successful and stops bleeding.
R17T9.7: Flanker successfully bites Murray for 6.

R18T27: Murray's displacement protects him against both of Girrigz' thrusts, and then Girrigz does something unexpected. He then bites ... and crits. For 26, 3 bleed, and a ruptured abdominal cavity.
R18T9.9: Murray, badly wounded, goes to flee. Girrigz misses, but the other wererat hits for 10. He goes 60', and then tries to staunch his bleeding again. And just barely succeeds. Because of the water, or even taking a few steps to get up onto the walkway, the enemies won't be able to get to him without him just barely making it out of there. With only 2 hit points left, Muhrbala lives to fight another day.
