List of Craft Essence and what they do
Note: If you feed a Craft Essence four duplicates, it will fully ascend (i.e. you will see 4 lit crystals), which means its max level cap unlocks in addition to boosting the passive effect it provides. Further duplicate feeding provide no benefit beyond extra experience for the Craft Essence. Passive Effect boosts do not occur unless the item is fully ascended.
Also, beware of bad name translations.
