Auto Battle

This is unlocked a little while after you start the game, you can utilise it to progress through battles a little more quickly. The idea is that for simple battles you can just activate Auto Battle and things will just progress based on the game's decision and without any of your own strategic decision making.

You can still select which enemy you would like to focus on during Auto Battle, just tap on the one you would like to hit, but that's all you can do!
