Boss Checklist - Eternal Battletowers Compatibility
Boss Checklist - Eternal Battletowers Compatibility is an addon that lists the Tower Guardian bosses from Eternal Battletowers in the Boss Checklist interface.
What it does
The addon integrates the Tower Guardian bosses of Eternal Battletowers into the boss checklist screen provided by Boss Checklist. Both Eternal Battletowers and Boss Checklist are required dependencies, so both must be installed for the addon to work. It is available for 1.20.1 on Fabric, Forge, NeoForge and Quilt, and the code is released under the MIT License without being open source.
The Eternal Battletowers data pack is bundled with the mod. On load, the addon creates an unspawnable placeholder entity that serves as the base for a Boss Checklist entry. A boss's entry is marked defeated automatically once a player earns the advancement tied to defeating a Tower Guardian. Because the addon supplies that placeholder itself, the Tower Guardian entry appears whether or not Keebsz's Battle Towers is installed, and the bundled data pack is not shipped with other Boss Checklist addons.
The addon runs on the client and the server together, so both sides need it. Files are published for 1.20.1 only, with version 1.0.0 as the latest file, released 2025-12-09.
Key features
Tower Guardian checklist entry
Tower Guardian appears as its own entry in the Boss Checklist screen, next to other bosses that the checklist tracks.
Automatic defeat tracking
An entry is marked defeated when the matching advancement is earned, so players do not have to update it by hand.
Placeholder boss entity
An unspawnable placeholder entity provides the base for the checklist entry and does not appear in the world.
Bundled data pack
The Eternal Battletowers data pack ships inside the mod, so the boss entry is available without a separate install.

Eternal Shield Bead is a Forge mod for 1.20.1 under the MIT License, and it is open source. Both are alternatives in a broader sense, while this addon only adds the Tower Guardian bosses to the checklist.
