Going back to Mirages as a whole, they do have their own way to learn their abilities largely in place of normal leveling.

This may look very familiar to those of you that have played FF X. Like the sphere grid system of that game, you gain SP from fights and mainly leveling up which you use to unlock new abilities here (though you don't need items to do the unlocking with here, just SP).

This is the same mirage after I unlocked its stroll ability for 1 SP. Stroll itself isn't a battle ability, but one that can be used in the field itself so there's more here than just your battle abilities like Cure. There are also nodes for raw stat boosts like HP+.

Keen eyes may already spot two things of note with this screenshot.

1. Each Mirage has their own unique 'sphere grid' so they won't all have the same abilities.
2. Some nodes are empty ones akin to the ones in FF X that you can fill with whatever you may want or need the most to round them out.

Thankfully, even if you have a mirage on hand but they're benched then they still get exp after battle. around 80% iirc. Either way, it's worth it to keep them on hand just to keep within range of the party's overall level so that you can keep their mirage grid filled out just in case you need to swap them in for a certain opponent or you need to use a field ability that they have to be able to move ahead.

By the way, it may seem like I'm going very deep into the combat mechanics here than might normally be expected in a topic like this but I do like talking about that stuff. I also like giving people that want to know more about it something more to latch onto than a simple 'you make towers to attack other enemies' with. Now that the tutorial area is done and I'm moving on to the first real area, I'll be able to step a bit away from mechanics posting.

And go back to where we should be now, back to the funny.

Buddy, I'm trying to be a hero here. I don't have the time or brainpower right now to want to tackle legal contracts!

Not only that, but you're super lazy too? At least the tutorials in this game are more willing to actually be more helpful about these things than in most other games, at least for a moment before self-correcting lol.
