The maximum number of Sockets for an item is 2.

How can I get a socket item? You may get a socket item by killing monsters, upgrading your items in Twin City, or completing some quests. Such items can also be found in the lottery.

How can I socket or embed a gem? Artisan Ou in Bird Island (756,545) can help you socket your right-handed weapons with 100% success rate. He charges 1 Dragon Ball for the first socket of a weapon. The second socket in the same weapon will cost you 5 Dragon Balls.

New method to put sockets on "non-weapon" equipment: Blacksmith Lee in the Market (212, 211) will charge you 12 Dragon Balls to put the first socket in your equipment.
       To put the second socket in your equipment, you need to give a Tough Drill to Blacksmith Lee. Although the Tough Drill is very helpful in making a second socket, the chance of failure still exists. If it fails, the Tough Drill will turn into a Star Drill. When you collect 7 Star Drills, the second socket will be made on your equipment with 100% certainty.

The Tough Drill is for sale in the Shopping Mall.
