I am also working on an item enchanting skill at the moment which at the moment is a very basic system, it works as follows:
*Enchant an item with enchanting materials
*Gain exp in that skill
*Unlock better enchants
I've only created a few enchants for now just to showcase the system:
*Fire
*Ice
*Lightning
*Wind
This just gives the weapon a nice particle effect, added damage of a certain type(Havn't added resistances in yet) and also adds a nice title to the weapon eg. Short Sword becomes Sword Sword of the flame etc
I will add screen shots tomorrow
