Learn about the Mirage Arena in Among the Sleep, a challenging coliseum for battles and mini-games. Discover how to earn medals, level up, and unlock rewards.
The Mirage Arena is a large and challenging venue for coliseum-style battles and other mini-games. It is also the only place in Birth by Sleep that supports multi-player. You can participate independently with each of the three characters, starting as soon as you have completed the first real world. Finishing the arena with one character could easily take 10+ hours, so if you are going for 100% completion, you might want to get started early! Beware though: the later arena matches are harder than anything in the main story.
There are two main goals in the Mirage Arena. The first is to collect medals. You will get these for competing in any event, and they can be used to purchase rewards:

If you are interested in completing your Reports, see my recommendations for what to buy in the table above. Everything else can either be gotten a faster way or is not counted in the Reports. Bio Barrage is a grey area - it costs a ton of medals and it can be gotten by command melding, but only with a 20% success rate.
The other main goal of the Mirage Arena is to increase your arena level. As shown in the above table, this is required to purchase certain items. It is also needed to unlock certain arena matches. Here are the 29 requirements you need to meet in order to level all the way up:
- Gain 300 / 1000 / 3333 / 5555 / 7777 / 9999 Medals (6 level ups)
- Complete each of the first 12 Arena Matches (12 level ups)
- Complete 5 laps of Country Chase in 2:30 (1 level up)
- Complete 5 laps of Disney Drive in 5:00 (1 level up)
- Complete 5 laps of Grand Spree in 5:00 (1 level up)
- Complete 5 laps of Castle Circuit in 5:30 (1 level up)
- Win each of the 7 Command Boards (7 level ups)
Note that the Rumble Racing and Command Board requirements can only be achieved in the Mirage Arena, but you have to play Rumble Racing in Disney Town as well to unlock it here.
If you are shooting for Level 30, the toughest requirement to get is 9999 Arena Medals. You will have to redo events a fair amount in order to get that high. Fortunately, if you spend medals, they will still count towards your total, so there is no need to save up.
MEDAL GATHERING TIPS:
- You get 15% more medals in the Arena Matches if you have multiple players, OR if you trick the game into thinking you do by using Group Cure abilities! So when you are doing arena matches, ALWAYS bring along Group Cure or an upgraded equivalent!
- One of the best ways to get Arena Medals is to play the Secret Command Board up to 35000 medals. Winning should get you the maximum 999 medals or close to it, and it shouldn't take too long. Just be sure to set the speed to Fast in the Command Board options! You might also consider raising the GP count the one time you do each of the other Command Boards. The GP starts rolling in quite quickly after a while.
- You can also make a couple elite commands like Mega Flare and do the hardest match that is trivialized by them.
