Molten Colosseum World 5 - IdleOn

October 2, 2025

Molten Colosseum is the World 5 Smolderin Plateau Colosseum that allows you to defeat waves of monsters for Treasure Chests that hold useful rewards. Colosseum runs are a great way to boost your resources when you first reach a world, so check out the drop tables below.

The Molten Colosseum is located in Smolderin Plateau / Niagrilled Falls (the second map of World 5).

It costs 10 Tickets to enter the Molten Colosseum. Colosseum Tickets work across all Colosseum so ones you earn from World 1 and World 2 also work for World 3.

Unlike previous Colosseums, you do not get daily tickets for this one. Instead, you'll need to use tickets from previous Colosseums.

Molten Colosseum Waves

You have 2 minutes and 30 seconds to complete all waves for the Colosseum. There are a total of 25 waves to defeat.
