Upon winning, you will acquire BP and rank points depending on the difficulty that you selected.
※Points will be reduced when allies are defeated in battle.

BUFFs can be activated by consuming BP.
The effects are valid until the reset at 5 AM.

※When you obtain the counter, "Damage Reflect" is displayed.
[Floor with a Treasure Chest]
You may obtain Trial Medals from the Treasure Chest.
※You can still challenge the stage even if you lose the battle. However, since the battle will start as continuation of the last progress, the defeated fighters cannot be used.
