Boss Checklist - Mob AI Tweaks Compatibility
Boss Checklist - Mob AI Tweaks Compatibility is a server-side addon that lists the Ominous Phantom, Elder Guardian, Ravager and other reworked bosses in the Boss Checklist interface.
What it does
The addon links Mob AI Tweaks and Boss Checklist. An entry flips to defeated as soon as the matching phantom is slain. Both Boss Checklist and Mob AI Tweaks are required dependencies, so both must be installed on the server.
Internally, the addon relies on a hidden stand-in creature that cannot be spawned and serves as the base for the checklist entry. Since this addon creates the entry rather than Mob AI Tweaks, the Ominous Phantom entry appears whether or not Mob AI Tweaks is installed, so players never have to stumble on the boss by accident later. The addon is built for Fabric, Forge, NeoForge and Quilt, with files for 1.20 and 1.20.1 and a NeoForge file for 1.21.1. It is released under the MIT License and is not open source.
Key features
Ominous Phantom entry
Adds a checklist entry for the Ominous Phantom, a vanilla phantom with new properties from Mob AI Tweaks.
Automatic defeat tracking
The entry switches to defeated without any manual step once the matching phantom is killed.
Reworked boss entries
Entries for the reworked Elder Guardian and Ravager are added to the checklist, with their loot listed where it applies.
Independent of Mob AI Tweaks
