This was submitted for the Goblin Artisans design challenge for the Britannian Faction. This is reubencovington's Retribution mechanic.

Seems pretty interesting. The one strike against it is that fear of it could dissuade people from attacking.

Jay seems to have similar concerns to mine. He said in the review,

> Retribution is the opposite of bloodthirst. Simple but important tweaks to existing mechanics are an excellent place to look for new mechanics and the flavor of a dominant force girding its followers further after an attack from dissidents is pretty strong. It's also quite white-black. There is a very big negative for retribution, though, and that is that instead of encouraging hesitant players to attack, which is both generally more correct and helps games to end, this keyword discourages attacking and will lead to longer games and more stalemates.

I fear he's right.
