Solo LifeSteal

Solo LifeSteal brings the classic LifeSteal loop to singleplayer worlds and small Fabric servers: every death costs a heart, and a crafted Nether Star Heart restores one.

Features

• Deaths remove a configurable number of hearts.
• Players can recover hearts by crafting and using Hearts.
• Optional ban-on-zero mode for true LifeSteal elimination.
• Admin commands for heart management, settings, and recipe editing.
• Chest-style recipe editor opened with /lifesteal recipe.
• Shared settings are saved in the instance config folder so they carry between worlds.
• Player heart totals are saved per world.

Admin Commands

• /lifesteal - show current settings.
• /lifesteal recipe - open the heart recipe editor GUI.
• /lifesteal settings startingHearts <1-40>
• /lifesteal settings maxHearts <1-40>
• /lifesteal settings deathPenalty <0-20>
• /lifesteal settings banOnZero <true|false>
• /lifesteal settings announce <true|false>
• /lifesteal add heart <player> [amount]
• /lifesteal remove heart <player> [amount]
• /lifesteal set heart <player> <amount>
