WARNING! I'm currently rank 102,Crafting the verdeus buckle in order to get the Torn Sash will literally equip all your combat units with it if they have a lower rank accessory (they will overwrite Boggart's Charity, Kobold's Kindness, Cloistral Belt, Power Belt and prevent you from equipping any future units with rubber belt), Crafting Kobold's Kindness and disassembling it for the torn sash did not overwrite anything.
Can someone explain this? I think crafting white equipment when you're above their BR will clone it to all party members, I crafted Kobold's kindness and none of the units equipped with linen belt upgraded to it. I tested this with Gabriel, he had a Bracelet of glazing and the moment I crafted a Bracelet of Grooming he was equipped with one. This explains why everyone was equipped with Linen Belt(from the slave traders quest) and stormbolt Earrings.
The only thing I can't confirm is if crafting a rank 105 white equipment for example when you're rank 104 and upon reaching BR 105 will overwrite colored accessories on the units, I will test this when I'm there.
