The insult is lost on the mimic, whose mother is a pile of magically animated ice.

[spoiler]Evaluating threat levels:
Stony humanoid: moderate
Pointy-eared humanoid: negligible
Shadowy humanoid: negligible
Invisible foe(unknown type): massive
Calculating projectile origin: origin is 5 ft x 10 ft region inside darkness. Maximum odds of successful assault: 24%
Evaluating next threat: Stony humanoid.
Location known. Within double assault range. Maximal odds of successful assault: 95% per assault.
Optimal attack pattern: double assault on Stony Humanoid[/spoiler]
The mimic's flexible form creates two arm-like protrusions which come as Kerasot for a one-two punch.
2 slam attacks on Kerasot (1d20+9=12, 1d20+9=28)The first slam misses by a good margin, but the construct recalculates its aim for the second attack, scoring a successful hit. However the hit is a glancing blow, and even as it tries to grab the stony humanoid, it has trouble getting a good grip.
slam damage and grapple: apply your DR (1d8+4=6, 1d20+13=17)Kerasot: roll a 2 or whatever you need to beat that-or tie. You have the higher modifier so you win ties.
Edit: just checked Kerasot's sheet. He ties on a 1, and 1 is not a failure for grapple. The mimic fails.
Kaz is up(delayed but never took his action last turn=same init, I think).
