Chest Thief
Bring danger to your storage with the Chest Thief — an outcast trader who steals your most valuable items and vanishes into the night. This mod adds a new hostile mob that sneaks into bases and villages, turning your loot into a constant risk.
Описание

Your chests are being robbed. The thief doesn't vanish — it takes your loot to a real underground dungeon you can raid to get it back. On a multiplayer server, everyone's loot ends up in the same place — and whoever gets there first takes everything.
Your base is a target.
A thief spawns near player chests, steals at night, and disappears. The more you own,
the more often it comes. Secure your base — or go on the offensive.
Find the dungeon.
Stolen items accumulate in a criminal base somewhere in your world, packed with loot
from every chest in the area. A Wandering Trader sells a map. Fight through the guards
and take it all — including what was stolen from your neighbours.
Run your own operation.
Kill the guards, mine their chest with a Silk Touch tool, and bring it home. Thieves
will start delivering stolen goods to you instead. On a multiplayer server, nobody
needs to know it's there.
Use the thief as a spy.
Put a lead on a captured Chest Thief and it will walk you toward the nearest chest it
can find — a dungeon, a hidden cache, or another player's base they thought was secret.

first launch. New fields added by mod updates appear automatically with sensible defaults
— no manual migration needed. All values can also be changed via the Cloth Config
in-game screen.

what gets taken first. Set stealOnlyListedItems: true in chest_thief_config.json
to restrict stealing to listed items only.
Default priorities (highest to lowest): Nether Star, Elytra, Enchanted Golden Apple, Totem of Undying, Beacon, Netherite gear, Diamond gear, Gold, Iron, Ender Pearl, and more.
