Unsounded, quite possibly the (2nd) best webcomic I have seen.

[Proud Tortoise]

Looks like he has a new pymaric leg.

In fact, that is just his leg brace... he's got some major repairs to be doing.

It's his code of conduct. Duane is not a big believer in asymmetrical combat: he matches physical force with physical force, pymary with pymary, and Sette's verbal barbs with his own brand of snarking.

So... insane, would be my guess.

My question is "Why didn't he do that in his pymary duel?" Is it against the rules or something?

Quiggers could simply have dodged it though, or countered it (although that would've been more difficult since Duane is a tacit caster). Taking an aspect from an opponent requires accuracy. Sette could probably have dodged it herself if she was at all expecting it.
