Oh, Snake Eyes has died more than once a turn. He's on a funky radical bombtrack. Burn, burn, yes ya gonna burn!
Oh wait ... Abysia likes burning.
(Anyway, with Phoenix Pyre up, if you are killed, then you are resurrected on the battlefield with extra fatigue. When you run out of fatigue, then you die for real. Except when immortals die for real in their own dominion, they don't die, they just get sent home. There is a tendency to pick up a few afflictions here and there though. Especially if you were minding your own business doin' a little readin' in the library, and all of the sudden the light of a baleful star shines through the window and curses you for life.)
