OOC: Now considering... I'm not so convince surrending is such a good idea. If you allow, I won't drop my weapon this turn, just speak and ready an action:
"Think of it, if I have truly disable twice your Clank and alone, now that I am not alone, what your chance to capture me? I just think we can talk like two civilized person, no?"
Kharas ready an action, if anyone come into melee to attack either him or Anvuss, he will attack him.
OOC: I don't make much hope of the talk, with my super charisma bonus (-2 actually) it won't go far.
