What's new

What's new! ✨

🐍 The Hydra

 

Win the NAUMACHIA to earn the Hydra Gem. Give it to Titus, then find the Colosseum Prison.

She starts with one head. Hitting her harder is not the answer.

...beat her for Hydra's Staff and the End Key.

🌌 The End Colosseum

Bring a Colosseum and the End Key to Ciocca. He knows what to do with them.

...Domitianus is waiting inside.

 

πŸ‘‘ Challenge III – APOTHEOSIS

Domitianus wants you to reach the sky, against the clock.

No elytra. He will notice.

...win it to earn the Chimera Gem. The Chimera is coming soon...

 

πŸ”₯ The Phoenix

It's finally here. Look for it in the Nether and tame it with a Lava Cookie.

...if it falls, it comes back.

πŸͺ“ New Battleaxes

  • Glowstone Battleaxe
  • Poisonous Potato Battleaxe – poison that spreads

πŸ“– A New Colosseum Guidebook
