Summoning Duration: August 1, 2021 00:00 ~ August 15, 2021 12:59 JST
- Players choose from 12 available Lucky Bag Summon banners. Each banner's pool of servants is categorized by the period that the Servants were released and the classes they belong to.
- Only Premium (paid for) Saint Quartz can be used to summon in the Lucky Bag Summon banners.
- Players may only roll on one Lucky Bag Summon banner.
- Players are guaranteed to summon one Limited 5★ Servant and one 4★ Servant from their chosen banner's pool of servants. It is possible to summon more than one 5★ Servant or one 4★ Servant on the chosen Lucky Bag Summon banner.
- 5★ Servants summoned will be picked among those featured on the banner, matching the banner's period and classes.
- 4★ Servants summoned will be picked among those released in the banner's period, regardless of class. So if a player summons from a Three Knights banner, any summoned 4★ Servant(s) can be of the four Horsemen classes.
- 3★ Servants summoned will be picked among all classes in the banner's period (as seen below), including Story Locked 3★ Servants but excluding Limited 3★ Servants.
