Ribbon is an accessory in Chrono Trigger. Equipped on Marle when she joins the party, this accessory raises the wearer's hit by 2. It can be worn by any character.
Strategy
Since wielders of Bows and Guns include the Hit Rate in damage and accuracy calculations, the Ribbon is best suited for them. These characters include Lucca and Marle. Equipping it to other characters offers no observable advantage.
Name Origin
Marle always wears her hair in a ponytail, so a strip of decorative fabric would be necessary. Also, when in battle, having hair in one's face would impair one's vision and therefore lower the hit probability of their weapon.
