Enchanting

Relic quality (purple) items have an enchant slot which allows them to be enchanted in the enchant window (mage tower) in town. You first have to find the scroll with the knowledge of the enchant on it, and then spend purple crystals to enchant a legal item. Enchantments can be enchanted over, while it is a permanent change to the item it can be written over. Unique items can never have their enchantments added/changed.
