The 
VALIANT attribute is also referred to as Hero in in-game files. While characters who bear this attribute seem to play an important part of the story, the commonality between them, if any, is unclear. It is a special attribute (which consists of All-Round, Infernal, Valiant, and World attributes), which means it shares the same reserved spot in the outgoing Support Lineup as other special attributes.Valiant cards have modified damage multipliers when facing other cards of specific attributes. These multipliers are listed in the table below.

AR Equipment can only be equipped on cards that match its limitation criteria. Currently, no AR equipment has an Valiant attribute limitation.
