Spite

Name another player still in the game as your killer. It doesn't have to be the player who actually killed you - you can choose the opponent who you hate the most. If you are not feeling spiteful, you can skip this effect. Roll d100. The result is not an ability and happens immediately without using the stack.

1Your spite backfires horribly. Choose a player other than your killer at random. That player loses the game.
2 - 3The Gods take notice of your need for vengeance. Your killer rolls on Deadly Acquisition
4 - 5Your rage is too furious to be directed at a single player. All players roll 3d6 and take that much damage.
6 - 10If it is your killer's turn, you control the rest of their turn. Otherwise, you control their next turn.
11 - 15Your killer loses half their life, rounded up.

41 - 60Your killer loses 5 life.
61 - 70If it is your killer's turn, end the turn. Otherwise, they skip their next turn.
