QP クォンタムピース
"A Quantum Particle. A fluctuation in the spiritron that grants many possibilities. Used as fuel to conduct all sorts of magecraft. Used to level Servants/CEs/Skills/NPs"

Quantum Piece (QP / クォンタムピース) is a basic currency that is used for a variety of game functions, including leveling Servants and Craft Essences, reinforcing Skills, upgrading Noble Phantasms, and Ascending Servants. They are earned by completing Quests, burning excess cards, or as a common chest drop from most enemies in the game.

The Chaldea Daily Quest Into the Treasure Vault awards significant amounts of QP. Most Events also have a way to obtain large quantities of QP, as part of the event activities and/or as an exchange for event items.
