Enchantments

Items can have special effects. This includes randomly when they drop or are found in a shop, but enchantments can also be applied at the enchanter NPC. Enchanting an item requires elven runes, which are acquired by disenchanting already-enchanted items. The enchantment applied will be random, unless applied using a component (many effects can only be acquired via random enchanting; except on keltonite armor which can only get effects that are available via component-enchanting). The number of enchantments you can get from this is more limited, but more reliable. You cannot enchant an item that is already of blue tier or higher (blue, purple, "unique"/legendary).
