About this Mod

📖 Description

Boss Checklist adds a list of all bosses from your modpack to the game, which can be opened by pressing the keybind or the button in the pause menu.

The menu displays all bosses from various mods, which you can mark as defeated, or they will be marked automatically if the mod is installed on the server. For each boss, you can view their model/image, mod name, drops, spawn info, and other additional info.

This mod is primarily client-side, but can be installed on the server to automatically mark defeated bosses and keep track of recent battles.

ℹ️ Compatibility

The list currently contains 171 bosses and minibosses, arranged in a logical order from easiest to hardest. However, this isn't definitive, so if you think the order is wrong, you can let me know on GitHub or move a boss with Alt + mouse wheel scroll.

📋 How to edit the list?

Since version 5.0, the mod has an editor menu where you can add a new boss. Additionally, by holding Alt and scrolling the mouse wheel, you can change the boss's position in the checklist.

You can create an addon using the files from config/boss_checklist/overlap/; details are on the wiki.

🛠️ Configuration
  • Client: You can enable or disable progression mode, search bar, and the open button in the pause menu. The file also allows you to disable in-game settings menu, animations, some gui elements and y offset of the open button.
  • Server: You can disable statistics, saving the name of the boss killer and multithreading.
⚙️ Commands

/boss_checklist set_defeated namespace:id true/false – a server command that allows you to mark bosses for all players in the world (new players will also have them marked.)

Frequently Asked Questions

Boss Checklist server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

Is Boss Checklist compatible with fabric and forge and neoforge?

Boss Checklist officially supports fabric, forge, neoforge for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Boss Checklist – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Boss Checklist consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
