ZEssenceEater

What is this?
ZEssenceEater is a Paper event plugin. While the window is open, killing a mob copies that mobs max health onto you (clamped by config). Kill a flying mob and you get survival flight. Kill a ground mob again and flight turns off. Your essence (max HP and fly state) is saved and restored on join, respawn and gamemode return to survival.
Outside the schedule the absorb does nothing (with a short action bar notice). Bypass permission lets staff test anytime.
Drop the jar into plugins, start Paper once, edit plugins/ZEssenceEater/config.yml. Messages and action bars use MiniMessage.
Where it runs

• Yes: Paper 26.1.x (built on Paper API 26.1.2). Java 25 or newer.
• Usually fine: Purpur on the same game version as Paper 26.1.x.
• No: plain Spigot or CraftBukkit.
• No: Folia.
• Old Paper 1.21.11: not the build target. Update to Paper 26.1.x first.

Optional soft depends
Essentials (or EssentialsX). Not required to start.
If Essentials blocks survival fly, ZEssenceEater restores allow flight after join, respawn, world change and fly toggle so event flight keeps working.
How the event works

• Schedule start and end times plus timezone (default Europe/Kyiv, 12:00 to 19:00). Enable or disable the whole event in config.
• Broadcasts start, end and optional reminders while active.
• Essence your max health becomes the killed mobs max health, clamped between min and max HP (default 2 to 60 HP, up to 30 hearts). Survival mode only.
• Flight configurable flying mob list (parrot, phantom, bat, bee, blaze, ghast, vex, allay, ender dragon, wither by default). Auto start flight after a flying kill if you want.
• Persistence playerdata.yml stores max HP, current HP and fly flag. Batched kill notices and delayed disk writes keep farm spam lighter.
• World / mob filters disabled worlds and disabled mobs (armor stands and players blocked by default).

How to install

1. Put ZEssenceEater.jar into the plugins folder
2. Start Paper once so config.yml appears

4. Use /zee reload after edits (or restart)

If something breaks, tell me your Paper version, Java version, and the error from the console. That saves a lot of back and forth.
Thanks for trying ZEssenceEater.
