Chestbound Sentinel is a mod about companionship, protection, and clever item management. At its core is the Sentinel — a loyal construct you create and bind to a special container. Once linked, your Sentinel becomes the guardian of that storage, defending it from danger, collecting loot, and helping you manage items in ways that feel magical and intuitive. Its indestructible and unkillable and will lure mobs making them target it rather than you.

A key part of the system is the Lure Bundle: A Lure is a special item bundle that tells your Sentinel what to care about. By placing items inside the Lure Bundle, you define which mobs should hunt it. Or by placing a Lure Bundle with items in the void filter, which items it should filter or void. It’s your way of shaping the Sentinel’s behavior without commands or configs — just drop items in, and the Sentinel understands. And renaming using the list bellow can filter even more items.

Version 1.4 brings the biggest improvements to the Lure and Sentinel systems so far.

In version 1.5 there will be add even more things, one which is when you break the Linked Container it will keep items like a shulker box, but other things will also be added as I develop the mod.

What’s New in 1.4 - "Latest update"

Completely reworked the Lure System again — the Lure Bundle now clearly shows which items attract which mobs as you add them, and also shows what item are inside.
The Lure system are now data driven so a .json file have all the items and mobs linked.
Fixed Lure Bundle enchanting — Looting now works properly, and a few new enchantments are now added. Applied through the Smithing Table with an Enchanted Book.
The enchantment Lure attracts mobs further out, and the Riptide pulls watermobs inwards.
The enchantment Mending now repairs items inside the Linked Sentinel Container when mobs are killed.
Added a new Geode Survey Map that is only obtained with fishing, and is a treasure loot drop, and it will show the nearest Amethyst budding block/geode. If the map cant be used, no amethysts are near. Try again in a different chunk.
Added a few new Sentinel Interface buttons, including a off/on to the Lure so mobs dont get attracted, a off/on killing of Baby animals/mobs.
Fixed a few "behind the scene" mechanics that did not work as intended before.
Mod is tested on a minecraft server and works fine.

Renaming Your Lure (Advanced Filtering)

The Lure Bundle can also be renamed to change how the Sentinel interprets the items inside it. Different names unlock different filter modes, letting you fine‑tune exactly what the Sentinel should match, ignore, or exclude. When you have renamed the Lure Bundle you place items inside and place in the Void Filter. Hover over to see what item you have placed. More information on what filter is used will come in a later update.

Here are the special names you can rename the Lure Bundle and use right now in v1.3 and above, some might not work 100% like you expect, but test with a few junk items:

allow – Only allow items that match the content
not – Exclude items that match the content
exact – Match items exactly, including NBT
!exact – Match everything except exact matches
ignore damage – Ignore durability when matching tools
type – Match by item type (e.g., all swords, all pickaxes)
tag – Match by item tags (e.g., #minecraft:logs)
nor – Advanced mode combining multiple conditions

These names let experienced players build powerful, flexible filters without any menus — just rename the Lure Bundle and the Sentinel adapts instantly.
