The Cinder Colossus

The Cinder Colossus, a giant wither skeleton, guards the Rift Spire. You must help defeat it once to enter the Spire.

  • Type /boss cinder colossus (or /boss colossus, /boss cinder), or talk to Kael at the Spire camp and pick Challenge the Cinder Colossus. The Colossus statue beside the Spire bridge opens the boss menu too.
  • The whole server sees “name is challenging the Cinder Colossus at the Spire Gate!”. Anyone can join within 2 minutes by typing the same command. Then the fight starts with everyone who is there.
  • The fight takes place before the gate of the Spire, on a floating arena.
  • /boss leave takes you back to the lobby.
  • After a fight the Colossus needs 1 minute to recover before the next challenge.
  • If your gear is far below its Level (30), it asks first, with tips. You can still go.
  • You keep your inventory in the arena. No PvP, no building.
  • Up to 15 minutes.
  • To count as a victor you must deal at least 5% of its damage.

The Colossus has more health the more players are in the arena when it starts:

Players 1 2 3 4
Health 550 800 1,050 1,300
  1. Melee hits for about 9 (12 when enraged) and gives Wither. Milk clears it.
  2. Every 20 s, magma cubes appear around it (more in bigger groups).
  3. Below 66% health: every 12 s a fire ring erupts from 3 to 8 blocks around the boss (6 damage and burning). Stand very close (under 3 blocks) or far away (over 8) when the warning appears.
  4. Below 33% health: it enrages (faster, stronger), and meteors fall every 6 s on up to 3 players: a circle for 1.5 s, then 6 damage within 2.5 blocks. Keep moving.

Every special attack is marked on the floor for about 1.5 to 2 seconds before it lands.
