Mana Prisms are a rare currency that can be exchanged at Da Vinci's Workshop for various items.

The primary ways to obtain Mana Prisms are by completing Daily Event Quests or performing Friend Point summoning and Burning 3★ Cards( Servants, Craft Essences, Experience Cards or Status Up Cards). They are also occasionally awarded during events or as Login Rewards. See Rare Prism for 4-5★ burnt servants.
