Enchantments
An enchantment is the second thing a piece of equipment carries, alongside its gem. One slot each, and one only.
Where they come from
They are not crafted. Enchantment scrolls come from daily quests, from the enchantment chests the game sells, and from the Tartaros Crypts during the Trials of Olympus.
An enchantment cannot be taken out. It can only be dispelled, and dispelling destroys it — which, given the scrolls cannot be crafted, makes putting one on a piece a decision rather than an experiment.
Enchantment and gem cover the same ground: the same effects, the same eight levels, name for name. The enchantment bonus is weaker than the gem's.
