I have a full set of Ray units, I go to add a ring, and the option is grayed out. I got a tutorial to do so, defining the requirements of 12* units, and left rings. 12* units are in the game, and easily accessible. Several, if not all classes will heavily benefit from having a ring added to their units. Why is this feature not working as intended?
Yeah, this is definitely not working as intended at all and it seems to be like some switch that didn't get turned on into the Add Unit Skill option.
