For all of his stealth, Kerrano's nose does him little good. The massive dire weasel slinks through the water before it launches a deadly assault.

Surprise: The weasel launches out of the mud to bite Kerrano in his left calf for only 8, Kerrano's preternatural senses helping him from the full blunt of the surprise attack. What he can't do is shake the Scribe off his leg and takes blood drain for 3 CON.
R1T26: Continuing to hold on, Scribe does 13 as he shakes violently and blood drain of 3 CON. With the massive loss of blood, Kerrano is already feeling weak.
R1T12: Needing as much help as he can, the Kerrano shifts to his weretiger hybrid form, and tries desperately to tear himself from the massive weasel's grip, but to no avail.
R2T26: Though the Scribe maintains his hold, his bite is not enough to cause more physical damage. However, he is still firmly attached and draws 4 CON from the weretiger assassin.
R2T12: Again, Kerrano is desperate and scared, and instead of trying to free himself, the Chelaxian is willing to go to blows; but, as powerful as he is, he is no warrior and his opponent's lithe and long body just keeps rolling and twisting out of the way.
R3T26: The hold is maintained, but again no damage. As before, though, having been attached previously still allows him to draw blood for 4 CON. Kerrano is almost drained.
R3T212: Truly terrified for his life, Kerrano - who is no stranger to biting and holding with his own teeth - again tries to escape, but again fails for feeling faint of blood.
R4T26: This time, perhaps because Kerrano is becoming lethargic, the Scribe tears open into the leg for 4, and does 3 CON. The blood loss is enough to kill him while Kerrano gives out a cry.
