Saint Quartz is Fate/Grand Order's premium resource.
Aside from summoning, a single Saint Quartz has the following uses:
- Gain 100% of your maximum AP. This will temporarily allow you to have more current AP than your maximum AP.
- If defeated in battle with 2 or fewer Command Spells available, revive your party to full health with 100% NP.
Saint Quartz can be acquired in many ways, such as:
- Purchase with real money (JPY only)
- Logging in daily
- Completing quests
- Event rewards
- Exchanging Saint Quartz Fragments
- Raising your servants Bond Points to a certain level
- Maintenance compensation
- Special occasions determined by game administration
On rare occasions, there is a use specifically for "purchased" Saint Quartz. Only a portion of quartz purchased with real money can be used in these cases. When prompted to spend quartz in-game, non-purchased quartz will always be consumed first.
