amiibo Journey (called Send on a Journey in the amiibo menu) is a mode in Super Smash Bros. Ultimate added in version 3.1.0 in which an amiibo can be sent on a journey via the Internet to fight against other amiibo. Three battles take place in one journey. In each of these battles, up to 3 other training partners can be fought at once. As usual, they will be able to gain experience. Once the amiibo returns, it will give the player gifts it earned from battling. The amiibo cannot be watched fighting when in a battle, but a replay can be seen after the battle is finished. However, the replays cannot be saved.
Players can only send one amiibo on a journey every 20 hours. The amiibo will not be placed against amiibo of similar levels.
After sending the amiibo on the journey, the game and Switch cannot be used for the duration of the experience, which can take as long as 3 hours. Due to its long duration, lack of reward, and inability to use the console during it, most players prefer training their amiibo themselves as opposed to using amiibo Journey.
