Raids & Bosses

Giant Monster Island bosses everyone fights together, and what they give.

A raid is a fight against a giant boss on a Monster Island. Everyone nearby fights it together. The more of the damage you deal, the better your rewards.

Raids give lots of Bones, money and Enchant Scrolls, and they are the only place to get some rare gear and enchants.

How a raid starts

You don't start raids yourself. The boss appears on its island on its own once enough players are there. To get there, open the Server Menu (the item in your last hotbar slot, or type /menu), then tap Teleport → Monster Islands. Bring friends.

Raid rules

  • The bar at the top shows the boss's health. The list at the top right shows who has done the most damage.
  • Your damage share is how much of the boss's total damage you dealt. A bigger share means a better reward tier.
  • One hit can only take a small part of the boss's health, so everyone gets a fair chance.
  • Type /monsters to read every boss's attacks before you fight.

Don't die

If you die during a raid, you get no rewards from it. Back off and heal when you're low.

When the boss falls, the whole server sees it in chat, and your rewards arrive straight away:

Sand Colossus Defeated

Sand Colossus

The Desert Island boss and the easiest raid. You need 10 Colossus kills to unlock Frozen Island.

Halloween bosses

During Halloween, the Archdemon and the Vampire Dragon take turns on Halloween Island. A new one comes 60 seconds after the last one dies.

Archdemon

Orange marks on the ground warn you; red marks show where it hits. Move away from its slam, then jump the shockwave. Hit it while it grabs someone to free them.

Vampire Dragon

Sidestep its bolts and dive. Later it lands as the Vampire Lord. Hit it while it drains health to stop the drain.

Deal at least 20% of the damage to get rewards: 1,200-1,680 Bones, $2,346-3,036, and some Diamonds, Emeralds, Iron, Gold or Netherite Scrap.
