Challenge Battles have arrived with Volume 2 of the Xenoblade Chronicles 3 Expansion Pass. When talking to the Nopon Archsage, you can choose which challenge you would like to take on, as well as the difficulty of the challenge. Each challenge will provide Noponstones as a reward depending on how fast you can complete the battle. If you get an A Rank by finishing the battle within a certain time, you get a unique reward.
These rewards can only be obtained once, but will stay in your inventory for the rest of the game. These include special swimsuit outfits for the characters, as well as powerful accessories that can only be obtained through Challenge Battles. The full list of unique rewards for each challenge is as follows:

To access the swimwear costumes, go to the menu and select Characters > Clothing for the respective character whose swimsuit you have unlocked. Go to the bottom where you will find the character’s DLC outfits, and equip their swimsuit from there. There are two variations of swimsuits, with the A variant easier to obtain while the B variant requires some training.
Getting the Swimsuit A variants will require you to be between levels 20-40. The Swimsuit B variants will require you to be between levels 50-70. Fortunately, you can always adjust the difficulty if you are struggling, especially if you just want to go to Easy difficulty for the swimsuits. The same can be done for the remaining battles, though they will still be a challenge on Easy.
