Restraint (こうそく Kōsoku) is a keyword introduced in Booster Set 1: Descent of the King of Knights.

How it Works

A unit with the "Restraint" ability cannot attack while it is on the indicated circle. Nearly all units with "Restraint" have a condition that can be fulfilled or a cost that can be paid in order to remove "Restraint" temporarily.

"Restraint" is generally found on units with much higher [Power] Power icon than other units of their grade (for example, a grade 2 unit with "Restraint" may have [Power] Power icon 11000), to balance them out with other units of the same grade.
