Battle Arenas are a feature introduced in Super Smash Bros. Ultimate that allows players to congregate in an online room. Rooms may have up to eight occupants, though only one battle can occur at a time. Players are able to freely change their character, stage, and preferred match rules.
Starting in Super Smash Bros. Ultimate’s version 3.1.0 patch, Battle Arenas began allowing Figure Players to participate in matches. Assuming the amiibo toggle is set to on, a FP can take a player’s place and play a match on their behalf. It is thought that Figure Players continue to learn from opponents if their Learning is set to on, though their progress cannot be saved in any way.
Unfortunately, Battle Arenas lack hack checks of any kind, meaning Figure Players with blatantly illegitimate stats (32,000 Attack and Defense, for example) are permitted to participate. Furthermore, it is impossible to turn off Spirits or even see an FP’s Spirits screen; this opens a possibility for trainers to subtly “sneak” Spirits onto their amiibo to cheat in vanilla tournaments. As a result, many tournaments are still held via Amiibo Powersaves.
Players are advised to be cautious around opponents who use Mii Fighter amiibo in Battle Arenas; if their Mii data is corrupt when they are summoned into battle (which can generally only be done purposefully), all Switch consoles connected to the room will crash to the home screen.
