Truse shifted as they attacked - more or less in a wrestler's pose. He gave half a nod towards the aid he was getting - and, focusing on reducing targets, delivered a fierce blow at the adjacent pawniard.
Truse's attempt to block for Douglas: (1d20)
Truse's karate chop attack roll: (1d20)
Truse's karate chop damage roll: (1d10+35)
Edit: And that's an almost certainly unnecessary critical hit.
