If you break your armor, ring, weapon, etc., the only way to repair it is by using Etheral Restoration stone.... Since my home town is Horizon you can buy this from the the npc Merchant Darby....
procedure: Click combine in your inventory, put broken item in the main slot, then Etheral Restoration stone(should be equivalent to the rank of your item) + then the item identical to your broken item, then click combine.
Repairing broken item may fail.... in my experience i failed in repairing my item... my advice, if you see your items durability level is low, better you start recovering your durability.
