Small new hack here that adjusts staff xp to work like it does in Shadow Dragon. Instead of using the staff’s gold value, like most versions of the FE7 ROM, this system calculates a staff’s bonus xp from a table at 0xCB528. Staff XP is reduced by 1 for every four levels the unit has, then divided by 2 if the unit is promoted.
I can make an FE8 version too, if anybody wants it.
