BossMode

Four bosses. Four altars. Beat one to unlock the next.

Build an altar, place the right item in the middle, right-click it — and something very large comes out of the ground. Each boss drops what you need to summon the one after it, so there is a proper order to work through.

🗿 The Golem King — 200 hearts

Fifteen blocks of stone with obsidian fists and a spiked mace. He shakes the ground when he walks. At half health he calls up Corrupted Iron Golems.

• Mace Slam — a shockwave that launches you
• Laser Eyes — twin burning beams that track you, but stop at walls
• METEOR SLAM — he leaps into the sky and lands like 20 sticks of TNT. A ring of fire shows where. Move.

👁️ Corrupted Herobrine — 150 hearts

Fast, player-sized, and he plays dirty. The sky goes dark when he arrives.

• Blink Strike — vanishes and reappears behind you
• Darkness — blows out every torch near you and blinds you
• Void Bolts — dodgeable if you keep moving
• Holograms — rings you with eight perfect copies of himself, then hides among them. Hit one and it puffs into smoke.
• At half health he splits into shadow clones

⚔️ The Corrupted Samurai — 175 hearts

The fastest of them, and he picks his weapon by how far away you stand, so camping at one range does not work.

• Far — a fan of throwing stars, and a barrage of 14 real arrows
• Mid — draws a line of fire on the ground, then dashes along it
• Close — a nunchuck flurry
• Sword Slice — his main attack, and it only lands in front of him, so getting behind him is worth doing
• At half health he drops the nunchucks and draws a second sword

🩵 The Corrupted Mutant Warden — 1000 hearts

Twenty-five blocks tall, with a ten-block sculk sword. He hunts by sound, so hiding does nothing, he moves faster than you can sprint, and he never stops attacking.

• SONIC BOOM — goes straight through walls
• Every attack the other three have, all of them
• At half health he summons iron golems and shadows at once

⚒️ Weapons

Each boss drops its own, and they are craftable too. Right-click for the boss's own move.

🛡️ Armour

Four full sets. Wear all four pieces of one and you get that boss's power.

Mixing two sets gives no bonus — pick a boss and commit.

How to summon them

Lay a 3×3 of the altar block on the ground, then right-click the middle one while holding the key item.

Commands

⚠️ Requirements — please read this one

You MUST turn on Experiments → Beta APIs in your world settings.

Without it, Minecraft installs the packs and everything looks perfect — the bosses exist, the textures are right — but nothing happens, because Minecraft refuses to run the script. It looks like a broken mod and it is not.

If it is working, you will see Boss Mode v1.0.0 ready! in chat a few seconds after joining. No message means Beta APIs is off.

Also needs Minecraft Bedrock 1.21.80 or newer, and both packs enabled (behaviour and resource).

Install

1. Download the .mcaddon and double-click it — Minecraft imports both packs.
2. Make or edit a world. Turn Experiments → Beta APIs ON.
3. Under Behaviour Packs and Resource Packs, turn Boss Mode on in both.
4. Play. Check chat says Boss Mode v1.0.0 ready!

If your browser renames the download to .zip, just rename it back to .mcaddon and it will work. This is the most common "it doesn't work".
