The listing gives Minecraft 1.21, 1.21.1. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Bosses' Addition

Description:

Are you bored of fighting the same old vanilla mobs? Bosses' Addition introduces 5 unique bosses, each one more powerful than the last! Face off against these customized vanilla mobs with increased stats and special gear. All of this is done entirely in vanilla Minecraft, no mods required!

How It Works:

Use /trigger easyboss to summon the easiest boss, balanced for iron-tier players.
Progress through harder bosses using /trigger mediumboss, /trigger hardboss, and /trigger extremeboss.
Challenge the Final Boss with /trigger finalboss—a massive, heavily-armored undead with a Soul Reaper Bow and 500 HP!
Each boss spawns above you and comes fully equipped with gear, weapons, and buffs.
