This is Training Mode! It is essentially a practice mode where you can control many aspects of gameplay!
Look at all of those choices!
There are a lot of options, ranging from item spawning to movement speed and even to enemy tactics!
There’s a help menu, too?!
You can toggle the camera between zoomed and stage-wide, too!
You can see everything from back here.
You can even test your skills against computer opponents! You can summon three of them and set them to attack. It can be quite a challenge.
How can you win!?
Training Mode is the place to go to get ready for the other modes.
