1. Charge your Ethereal Stone
First you need to put either a Big Ethereal Stone or Broken Ethereal Stone into the top slot of the combination box. Then in the slots below put any ranked equipment and a Ethereal-Charging Magic Catalyst (Yellow Stone). Once you hit confirm it there should be a Big Ethereal Stone or Broken Ethereal Stone (Black Stone) in your inventory with durability. This stone is used to repair your lost durability on items.
2. Repair your Equipment (Durability 1+/XXX)
It is very important to put the equipment needing repairs to be put in the top slot of the combination box. In the slots below put either a Big Ethereal Stone or Broken Ethereal Stone (Black Stone) that has durability and also an Ethereal Recovery Magic Catalyst (Blue Stone). Once you hit confirm your equipment should be repaired based off the number of Ethereal Recovery Magic Catalyst (Blue Stone) inserted into the Combination box and that same amount is deducted from the Ethereal Stone’s durability.
For example if you put a Broken Ethereal Stone (Black Stone) with 30 durability on it and 20 Ethereal Recovery Magic Catalysts (Blue Stone) to repair a Rank 6 Helmet with 20/64 durability. The result will be your Rank 6 Helmet with 40/64 durability, Broken Ethereal Stone (Black Stone) with 10/1000 durability and the 20 Ethereal Recovery Magic Catalysts (Blue Stone) will be consumed.
3. Repair your Broken Equipment (Durability 0/XXX)
First you put the broken equipment into the top slot of the combination box. The equipment has to have 0 Durability. Then in the slots below put an Ethereal Restoring Magic Catalyst (Green Stone) and an exact copy of the equipment being repaired. The equipment has to be of full durability or else the broken equipment will not be repaired. Once everything is the combination box and you hit confirm the equipment should come repaired with 1/XXX durability.
For example a Broken Rapid Bone Helmet has 0 durability and needs repairs. So you will need to have 1 Ethereal Restoring Magic Catalyst (Green Stone) and a Rapid Bone Helmet with 64/64 durability. If it has 63/64 and used in the combination box it will be consumed without repairing the Broken Rapid Bone Helmet.
