What's included in the Abyss Expedition boost
The runs in your order, at the Abyss Expedition level or Abyssal Defence clears you choose.
Every drop from those runs: Prototypes for Calamity weapons, elemental Crystals and Radiant Crystal Packs at the higher levels, and Abyssal Compasses.
Compass progress: each retreat gives a compass for the highest level cleared, so your next run can start higher.
Updates after each session, with the levels cleared and the Prototypes collected.
Not included: forging and upgrading the Calamity weapon itself, and the Trial Rank and quest that unlock these modes. For those, see the weapon unlock boost and the Trial Rank boost.
Abyss Expedition and Abyssal Defence
Both modes open together and both feed Calamity weapon upgrades, but they play differently.
Abyss Expedition | Abyssal Defence | |
|---|---|---|
How a run works | Activate the device, fill the Serum gauge by defeating enemies, then retreat or keep going for bigger rewards | A high-difficulty defence commission at the Calamity tier |
Levels | Lv. 100, 120, 140, 160, 180 and 200 | As listed in each offer |
Main rewards | Prototypes from enemies, an Abyssal Compass every level, Crystals of your chosen element from Lv. 120 and Radiant Crystal Packs from Lv. 140 | Calamity weapon upgrade materials |
Entry | One Abyssal Compass per run | As set out in each offer |
Hydro and Umbro stages are the only source of Hydro and Umbro Crystals, so tell the seller which element you need most.
Options
Option | Choices | How it changes the order |
|---|---|---|
Mode | Abyss Expedition, Abyssal Defence, or both | Choose by the materials your Calamity weapon needs next. |
Level | Abyss Expedition Lv. 100 to 200 | Higher levels drop more and have much tougher enemies, so they cost more. |
Runs | One run, a set such as five runs, or a farm until a Prototype target | More runs mean more Prototypes and Compasses. |
Compasses | Your own Abyssal Compasses, or forged by the booster | Only Lv. 100 compasses can be forged, so higher starting levels use the ones you've earned. |
Method | Self-play or piloted | Self-play: you join the booster's expedition in co-op, which costs you no compass. Piloted: the booster runs it on your character while you're offline. |
Platform and server | PC, iOS or Android, and your server | For self-play, your booster plays on your server. |
Requirements
Before you order an Abyss Expedition boost, check that you have:
Trial Rank 60, or a Trial Rank boost in the same order.
The Calamity He Wrought quest done, which also needs Floor 12 of Immersive Theatre cleared and a Gold Demon Wedge at level 10. The Immersive Theatre boost and the Demon Wedge farm cover those steps.
A team around level 80, with weapons and Demon Wedges to match, because enemies get much stronger at each level. The leveling boost gets it there.
How the DNA Abyss Expedition boost works
Choose the mode, the level and the number of runs, then pick a seller's offer.
Compare offers from verified sellers and check out securely.
Agree on a start time with your booster in the order chat.
Join the booster's expedition in co-op, or let the booster run it on your character.
Check your Prototypes and compasses, then confirm the order.
How long it takes
Every offer shows the seller's delivery time. A single Lv. 100 run is the quickest order. Five runs, higher levels and Prototype targets take longer, because the strongest enemies sit at Lv. 180 and 200.
Abyss Expedition and Abyssal Defence FAQ
What are Prototypes for?
Prototypes craft and upgrade Calamity weapons, such as Prototype: Thorned Requiem and Prototype: Perpetual Strife. They drop from enemies in Abyss Expedition, so the amount varies from run to run.
Can I join the booster's expedition instead of using my compass?
Yes. Joining another player's expedition in co-op is free, so a self-play Abyss Expedition boost lets you farm without spending your own Abyssal Compasses.
Should I retreat or keep going?
Going further gives better rewards, and retreating banks a compass for the highest level you cleared. Your booster plays each run to your goal, whether that's a safe Prototype farm or pushing to a higher compass.
Is there an "Abyss mode" in Duet Night Abyss?
The Calamity endgame is made up of Abyss Expedition and Abyssal Defence, both opening at Trial Rank 60. This page covers both, so whichever you call it, this is the service for it.
Can I learn these modes myself?
Yes. Book an endgame session through Duet Night Abyss coaching and plan the elements and teams for each stage.
