Hearts are currency too
Everyone spawns with ten hearts. Kill a player and you take one of theirs, up to a cap of twenty. Die to the world and you lose one. Hit zero and you are eliminated until someone spends a heart to bring you back.
- +1 heart per kill, capped at 20
- −1 heart on a natural death
- Revived players come back on 2 hearts
- Withdraw hearts as items — they can be traded, sold or stolen
