[Lord Pyre]

I don't mind seeing tests first, but I do think I would struggle to accept Mercy. Not only do I lose my figure, but there's a chance that they'll be used against me. I'd rather they die than you get them.

There could always be a d20 roll off to force-capture them to solve that, so you actually get to use the power occasionally. Or perhaps the opponent gets a boon if they accept mercy, like an initiative boost next round or something. I don't know the theme here though, if it's acceptable.

Dig the mechanics otherwise though.
