Laugh ~~~ I want to use this mode , too. But I have not found the solution. My idea is the way that resemble "manner_system", 1 + 2 + 4 + 8 + 16.............,but i don't know to edit it
i think that too,
1+2+4+8 will be good,
or maybe it can modified using array like EXTRA_BONUS[0,1,2,3....], so a character can have many effect.
