A loadout is a set of mods that you can save and move from unit to unit.
 
For example, you might have a set of mods with increased Defense and Crit Avoidance that you’d like to move between your tanking units.
 
To create a Mod loadout, tap Characters, then Mods, then Loadouts.
Tap + Create new loadout.
 
To create your new loadout, you can use unassigned mods, or mods that are equipped on another unit.
 
To make it easier to keep track of your mods, you may want to create loadouts for any unit you’re taking mods from before you move mods. That way you can easily switch them back if you need to.
 
There’s a credit cost each time you switch loadouts, and it increases each time you do it.
