The accessory path changes only impact new characters, who will see a change in the items they receive. New users will obtain the new Sterling/Ivorymoon accessories through epic quests, while existing characters will keep their current accessories. Existing characters can also acquire the new Ivorymoon accessories from the Silverfrost Valor Stone Trader NPC in Grand Harvest Square for 10 Silverfrost Valor Stones each.
