Duet Night Abyss Advenspheres — how they work and where to trade
Duet Night AbyssCollect region‑specific orbs across Atlasia and exchange them at Lunoxplorer after a simple quest unlock.
Advenspheres are floating collectible orbs scattered across Atlasia in Duet Night Abyss. Each region has its own type (and color), and those regional types are used as currency to trade for materials and upgrade items. You pick them up by walking up to an orb and interacting with it.
How to find and collect Advenspheres
- Look up: many Advenspheres sit on rooftops and other high points around cities.
- Don’t ignore underground routes: some spawns are in places like the Icelake Sewers.
- When you’re close, interact to collect the orb instantly—no combat or puzzle required.
Where to submit Advenspheres (Lunoxplorer)
Trade Advenspheres at the Lunoxplorer shop. You can reach it two ways:
- NPC: In Icelake Suburban Square, near Lunoeggy’s Impression Shop and beside the Square Teleporter.
- Menu path: open the in‑game Shop and go to Bustling Marketplace. This mirrors the NPC’s stock and pricing.
Trades consume the matching regional Advensphere type. Stock is limited on some items.
Unlock requirement for the Lunoxplorer shop
The Lunoxplorer exchange does not appear until you complete the main quest “How the Team Got Its Name.” If the vendor isn’t present in Icelake Suburban Square or the Bustling Marketplace tab isn’t offering Lunoxplorer exchanges, progress that quest first.
