How Dimensional Duel works in Girls Echo: Power groups, 10 attempts a day, the 5-rank challenge limit, all-in sweeps and season rewards for the top 50.
Unlock and seasons
Dimensional Duel opens at Player Lv. 30, Server Day 3. It runs in seasons across servers. Players who sign up are put in a group with players of similar strength (in-game help). Sign-up, grouping and the season end are timed by the server; the card counts down to the season end. The game files hold a value of 72, possibly the season length in hours (unconfirmed).
Your defence team is its own Dimensional Duel lineup, separate from Phantom Arena. Battles are worked out by the server.
Attempts
You get 10 attempts a day (in-game help; the game files agree). When you run out, the game offers to buy one with Diamonds and then fights at once. Unlike Phantom Arena, it doesn't use the Phantom Arena Challenge Ticket. The price comes from the server; the game files list 20, 30, 50, 70, 100, 100 Diamonds, possibly rising with each purchase (unconfirmed).
Who you can fight
The list shows your whole group, opening a few places above you. Players above you show Challenge, but only those at most 5 ranks above you can be challenged; the button is grey for anyone higher. While you have no rank, you can challenge anyone. Players below you only show Sweep.
A sweep uses all of your attempts left in one go, not just 5 as in Phantom Arena. Win and you swap ranks; lose and nothing changes (in-game help).
Season rewards
Rewards are mailed at the end of the season, by your rank in your group. Only the top 50 have a reward in the game files; whether rank 51 and below get anything isn't confirmed. The table has no group column, so the game shows the same reward for first place in the lowest group as in the highest; whether the server pays it that way isn't confirmed.
| Rank | Season reward |
|---|---|
| 1 | Diamond x2,000, Phantom EXP x500,000, Phantom Dust x1,000 |
| 2 | Diamond x1,350, Phantom EXP x350,000, Phantom Dust x650 |
| 3 | Diamond x1,000, Phantom EXP x250,000, Phantom Dust x500 |
| 4–10 | Diamond x500, Phantom EXP x175,000, Phantom Dust x350 |

| 21–50 | Diamond x100, Phantom EXP x50,000, Phantom Dust x100 |
Champion rewards
The Records screen counts how many seasons you finished first in your group. Each milestone pays once, claimed there. Dimensional Duel avatar frames and titles for 1, 5, 10 and 20 wins also exist; how they are given isn't shown in the game code (unconfirmed).
| Group wins | Reward |
|---|---|
| 1 | Summoning Oath x10 |
| 5 | Premium Summoning Oath x5 |
| 10 | Premium Summoning Oath x5 |
| 20 | Premium Summoning Oath x10 |
Groups
Each group has a tier named after its Power range. The group name shows at the top of the Dimensional Duel screen, and your past seasons are listed with group and rank under Records. Some names cover two ranges. Which Power the server uses for grouping isn't confirmed.
