Lifesteal Engine
by NeoAorus
Lifesteal Engine is a Fabric server mod that changes how hearts are gained and lost through player combat, with optional revival and anti-abuse systems.
What it does
Players lose hearts when another player kills them, and the killer gains them. The server sets the maximum number of hearts, and can limit heart loss to PvP deaths only. A player who reaches zero hearts can be banned for a configurable duration. Hearts can also be handed out as a heart item, and a leaderboard with stats tracks the results.
The revival system puts a player who would otherwise be eliminated into a downed state, where another player can bring them back, and it supports Revival Totem items. Anti-farm rules add an enable switch and a cooldown, so the same players cannot repeat heart transfers. Combat tagging marks a player who damages another player, directly or indirectly, and a logout while tagged can count as death. Respawn protection is available as well, and players get chat messages when combat starts and ends.
Lifesteal Engine runs on the server alone, so players join without installing it. Admin commands require operator-level permissions, and the mod is published for Fabric only, across three release versions, 26.1.2 – 26.3, under the MIT License; the code is not open source.
