Reputation (REP) is a non-combative stat used in the Yggdra Union series; only player units have this stat. Each time a unit wins a battle, they'll gain 1 REP point, which is represented by a "!". The cap is six (6) points. Once a battle is lost, that unit's REP empties back to zero (0). REP's purpose is to acquire trade items on certain Battlefields; some require a high REP total, others require a low REP count.
It is replaced by Pow. Up Pts on enemy units.
