Reversio is an enemy found in the Chromagar Cave on Shadra in Magical Starsign.

Profile
Reversios are large living disks. The white side displays an angry face, while the black side has a deviously happy face.

Enemy
Reversios occupy two slots in the bestiary, one for light and one for dark. When they are attacked, they switch to the opposite affinity. When they have light affinity, they will use either crystal laser in the front row, or blinding light in the back row, whereas with dark affinity, they will use shadow die regardless. Crystal laser strikes a single member of the party, and blinding light strikes all party members. Shadow die strikes up to three from the back row, and only one from the front.

Bestiary entry
Reversio monsters spin so fast, they can switch the alignment of the stars. Sandwich pieces of the same color to flip their color.
