Amphoreus Loot: How Treasure Chests Work

Each map in Amphoreus is stuffed with loot, but it’s not just about opening chests. You’ll spot a chest icon with a number in the top left corner of your map. That’s your progress tracker, but keep in mind—it only counts regular chests, not those hidden behind puzzles, tough enemies, or Spirithiefs.

Chests here usually give you Celestial Ambrosia. Exchange these at the Tides of the Basin in the Vortex of Genesis to level up and claim rewards like Stellar Jade or items for your Trailblazer. This works much like the treasure system on Penacony. No Warp Trotters or trash cans here—just keep your eyes peeled for Spirithiefs, who might try to nab your loot or challenge you to a battle!

Time Switching and 3D Maps: What’s New?

Amphoreus introduces multi-floor, 3D maps. Some rooms change between dawn and evernight, shifting chest and enemy locations. All chests are marked on a single map, but remember, you’ll need to swap between both time settings to find them all. Explore every corner!

‘Demigod Council’ Dawncloud (v3.2 update)

This area is long! The Spirithief up north steals a floating scroll, not a chest.
