I am pretty sure the attack did not hit Dalanath as well Sk4mpE.
Nan, Did you hit the Kruthik Young at Y19 or the Kruthik Adult that was at Y21? I had thought it was the one at Y19 so you could get the flanking bonus and sneak attack damage. The one that attacked you was at Y21 and after its attack moved one square on a shift.
Sk4mpE is correct if he had hit you since it is marked by his character the damage would have been reduced.
