Boss Checklist - Vampirism Compatibility
Boss Checklist - Vampirism Compatibility is a Forge and NeoForge addon that lists the Ancient Remains and Vampire Baron bosses in the Boss Checklist interface.
What it does
The addon connects two mods: Boss Checklist, which keeps a list of bosses and their status, and Vampirism, which adds the Ancient Remains cluster and the Vampire Baron mini-boss. Both Boss Checklist and Vampirism are required dependencies, so both must be installed for the addon to work.
Ancient Remains is a whole block cluster that a mob begins from, and the addon does not have to wait for the Vampirism spawn. Instead, a stand-in entity that cannot be spawned naturally serves as the foundation of each boss entry. The entry is marked defeated automatically once a player breaks the core block that ends the fight.
The addon is not bundled with other Boss Checklist addons because it relies on the stand-in entity the addon itself adds. As a result, the Ancient Remains entry appears in the checklist even when the Vampirism mod is not installed, so players do not discover the boss only after searching for it. Client and server both need the addon, and it is released under the MIT License but is not open source.
Key features
Ancient Remains entry
The Ancient Remains boss appears in the Boss Checklist interface with its own entry and status.
Vampire Baron entry
The Vampire Baron mini-boss is listed alongside the other bosses in the checklist.
Automatic defeat tracking
Breaking the core block that ends the fight marks the matching boss entry as defeated.
Stand-in entity
A non-spawning entity provides the foundation for each boss entry, so the list works without Vampirism's spawn logic.
