I've found two seperate entries in the rulebook concerning win/loss conditions, hoping you fine people could help me.
One says when you reduce your opponent to 0 Life, you win the game.
The other says if you start a recovery step with 0 life, you lose the game.
Which takes priority? If it's really the latter We've found at least every 3rd game ends in a tie.


Please Help!

The game does not end when one player reaches 0 endurance. Instead, endurance totals are checked at the start of the recovery phase.

Player 1 > Player 2 <= 0. Game: P1.
Player 2 > Player 1 <= 0. Game: P2

Player 1 < 0 < Player 2. Game: P2.
Player 2 < 0 < Player 1. Game: P1.

P.S. Ties are expressly prohibited in this game. Keep playing until one of the listed conditions is true.

Forgive me for reitterating, but for example, if on recovery, player 1 is at -19 and player 2 is a -15 player two would win?

That is correct.

Correct
