Using Craft Essences

Craft Essences (CE) are Conceptual Mystic Codes that extract the concept of magecraft so they can be attached to a Servant to grant them additional abilities. Equipping a CE to a Servant can grant them higher HP or ATK, or even special skills.
CEs can be obtained through Friend Point Summons or Saint Quartz Summons.
Just like Servants, CEs can be Enhanced, and combining other CEs will power up the selected CE. Combining identical CEs will raise the level cap of the base CE.
