The Dwarf took a deep breath, but was apparently distracted by the lump forming on his head. The dwarf charged and tried to destroy Nithrar's right arm with a back handed blow. Nithrar attempted to pass it and step in, but got a little ahead of himself and took the blow on his chest. Nithrar, cursing, finished passing the strike and launched his counter. Nithrar considered using a bit of magic to trip the dwarf up, but discounted the thought immediately. Instead, he decided to force the Dwarf into submission using more mundane tactics.
Seeing as how my char will not go for the killing blows in this situation, I would propose that no HP remaining will indicate a knock-out. Also, there must be a penalty for attempting a disarm, otherwise, why not try every turn. I would suggest no or half damage if unsuccessful. I'll assume no penalty for this fight...
Nithrar decides it's time to Defang the Snake.
Two strikes to the arm please
