+ /// after using a Spell
Asuka uses another of his currently equipped Spells.
Asuka removes one of his currently equipped Spells, or replenishes an empty one - doing the latter uses up 1 Bookmark stock from the currently equipped Test Case.
The version is the slowest, but doesn't cost anything to use; the version is quicker, but uses up Tension and the version is the fastest, but uses up health. Can continually increase the Mana recovery by holding the button.
Asuka changes his Test Case - each of the 3 specialise in different styles of play: (yellow) for projectiles, (green) for mix-up Spells, and (blue) for etc.
