Help Belts grow up quickly by expanding this article into a full one, and maybe it can one day be sexier than Etna. Try asking for details on its talk page.
Belts are an item to increase ATK. Usually, they also decrease DEF, (SPD in Disgaea 2 ) but in Disgaea 3: Absence of Justice, that negative side has been removed. In the first two installments, Belts were either Bonus prizes or items avaliable at the shops once the "Belt Inventory" bills were passed. To unlock the Belts section in the Armor Shop in Disgaea 3, you will have to pass the "Appoint Justice Legion NW "and have someone within that club. Also, Belts are a Succubus's favorite item to receive when bribing in the Dark Council.
