Girls Echo Abyss Prison Guide

Abyss Prison in Girls Echo: 200 boss floors over 6 difficulties, solo or in teams of 3, with Secret Treasure and daily rewards.

Getting in

Abyss Prison opens on Server Day 2, Player Lv. 28. Its button is in the play hall, and the Secret Treasure screen has a shortcut to it. The in-game help calls it Abyssal Prison and its rewards Mystic Treasures; they are the same mode and Secret Treasures.

Atonement Prison, another team boss mode, is in the game files but closed: the play hall shows Abyss Prison in its place, and every way into Atonement Prison checks a condition that never opens (Coming Soon). The Atonement Shop tab of the Explore Shop is closed the same way.

Floors

There are 200 floors, fought in order. You can only fight your current floor; clearing it moves you to the next. Each floor is one boss (Fifth Priest, Lion Dance, Yamata no Orochi, taking turns) with a recommended Power and a difficulty: Easy 1–30, Common 31–60, Hard 61–90, Abyss 91–120, Nightmare 121–150, Purgatory 151–200.

Floors 1–25 need Player Lv. 1. From floor 26 the level goes up every 5 floors, up to Lv. 420 from floor 196. A floor you haven't reached the level for shows the level it needs.

Abyss Prison has its own lineup, set with the Formation button. Until you set it, Battle and Create Team only say "No squad formed. Please go to Formation first." Battles are fought on the server, so there's no damage formula to show.

Rewards

Each floor's first clear gives 4 Secret Treasures and Glimmering Dust. Every block of 5 floors hands out all 20 pieces (5 slots for each of the 4 classes) once, at the same quality and star, and the quality and star rise every 5 floors, from Green 1★ at floor 1 to Red 10★ at floor 200.

The daily reward is Glimmering Dust (twice a floor's first-clear Dust) plus Abyss Firestone, 100 at floor 1 rising to 370. Claim it once a day with the Daily Reward button; after that it reads "Claimable Tomorrow". It can't be claimed before you clear floor 1. Which floor it pays for is kept by the server; it looks like your highest cleared floor, so pushing higher raises it (unconfirmed).

The seven-day newbie quests ask you to clear floors 5, 10, 15, 20 and 30 here. Abyss Firestone is spent on the Abyss Shop tab of the Explore Shop (the Shop button here goes straight to it). Its item description says Atonement Shop, but that tab is closed.

Teams and assists

A team has up to 3 players. You can only create a team on your current floor. Trying it from another floor's tab shows "Insufficient attempts!". That message has nothing to do with attempts; it only means that floor isn't your current one.

You can join teams on any floor you have reached or cleared, so cleared floors are where you help others. The team list has an All tab plus one tab per floor up to yours; teams can only be created from a floor tab. The leader starts the fight, can disband the team and can turn on auto start; other members can only leave. A team can send an assist request, which shows a help button to players who can join that floor. The in-game help says a team lasts 10 minutes.

Helping in someone else's team pays Abyss Firestone: 100 for your first assist of the day, then 5 for each one after that (the drop happens after 1 assist). Every floor pays the same.

Watching the fight

A fight only plays on screen if you are on the Abyss Prison screen or the team screen. If you're elsewhere, its rewards are claimed automatically the next time the game loads your Prison info. The result screen shows each member's damage and how much HP the boss has left. A loss shows Defeat and no rewards.

Attempts

The game shows no attempt count for Abyss Prison and doesn't check one before a fight. Whether the server limits fights per day is unconfirmed.
