How to add a socket to your Elven Ears?

Guys just follow this guide and you can obtain your sloted middle headgear.

To start any slot enchant process, you must bring the required items and Zeny to NPC Piercing Expert at 1st floor of Eden Group (coordinates 179, 47)

You must wear the item while talking with him.

Talk with him, and choose "Yes, I will."

Warning: If you have failed in the process, you will lose all items and Zeny.

If you succeed, you will get the new item with [1] socket.
