In Aion, there are three basic ways to enchant, or enhance, your gear. The first is using Enchantment stones, the second is using Manastones, and the third is using Godstones. In this guide, I will cover all three with much detail. Aion's system of enhancing your gear is quite different and more complicated than most other systems.

  The most frustrating part of learning how to enhance is learning that THEY CAN FAIL! Not only can they fail, but failing can have negative side-effects for your gear! This is why you must read the guide below so that you do not lose your time, your character's money, or your cool!
  Before you can use Enchantment stones, you must create them. In order to create them, visit a nearby and purchase Extraction Tools.
  One set of tools is used per extraction. In order to extract, you must Right-Click on the Extraction Tools and then Left-Click on the item you wish to extract from.
  There are some important guidelines! First, you can only extract from items that can be enhanced. These are your chest slot, legs slot, shoulders slot, hands slot, feet slot, primary slot, and secondary slot. Second, when you extract from an item, that item is destroyed. Do not extract from items you wish to keep or use, obviously.
  Once you have extracted an item, you will receive Enchantment stones. They come in the form: Level # Enchantment. The level corresponds to an item's level, not your level. The level of the Enchantment stone that you receive varies quite dramatically. Also, the rarity of the item does not affect the level of the Enchantment stone that you receive. For example, if you extract a Level 20 Green, you could receive 3 Level 25 Enchantment stones. Then, if you extract a Level 20 Blue, you could receive 1 Level 20 Enchantment stone. In other words, it's very random.
  Now that you know how to extract and create Enchantment stones, I will tell you how you apply them to an item. The first important part is figuring out the level of the item you wish to enhance. Quite simply, the item's level is the required level to use that item. This can typically be found just by looking at the item's statistics, as it will say what level is required. The item below has an item level of 27.
