The "Guaranteed Summon" feature guarantees that, in the case that you perform a Limited Time Pickup Summon 329 times without summoning the Pickup ★5 (SSR) Servant even once, the 330th Summon is guaranteed to be one copy of the Pickup ★5 (SSR) Servant.

 

If multiple Limited Time Pickup Summons are available at once, the number of Summons you have performed will be counted individually for each Pickup Summon (each page on the Summon Screen). In addition, if a Pickup Summon has multiple Pickup Lineups that are available during different periods, Summons will be counted individually for each lineup. For example, in a Daily Pickup Summon where the Pickup Lineup changes each day at 21:00 PDT (GMT -7)/20:00 PST (GMT -8), your Summon Count will be reset at the moment the Pickup Lineup changes.

 

The Summon Count for the "Guaranteed Summon" feature will be reset under either of the following conditions. 
- You summon the Pickup ★5 (SSR) Servant within 329 Summons.
- The Guaranteed Summon goes into effect on the 330th Summon and you summon the Pickup ★5 (SSR) Servant.
* Once the Summon Count for the "Guaranteed Summon" feature is reset, a new count to 330 Summons will begin from the next Summon.

 

Summons using Paid Saint Quartz, Free Saint Quartz, and Summon Tickets are all included in your Summon Count for a given Limited Time Pickup Summon. You can check your Summon History from the Summon Screen in question.

For details on the "Summon History" feature, please see this FAQ:

* The "+1 Bonus Summon" performed with each 10x Summon and the once a day "1x Summon" using Paid Saint Quartz are also included in your Summon Count.
* The "+1 Bonus Summon" and the once a day "1x Summon" are calculated separately for each Summon Lineup.
* The count for the "1x Summon" for one Paid Saint Quartz will be reset each day at 21:00 PDT (GMT -7)/20:00 PST (GMT -8).
* You can check your Summon Count for the "Guaranteed Summon" feature from your Summon History.

If you fulfill the conditions for the "Guaranteed Summon" feature when you perform an 11x Summon, one copy of the Pickup ★5 (SSR) Servant is guaranteed to be summoned. This goes into effect separately from the ★4 (SR) or rarer card and ★3 (R) or rarer Servant guaranteed with each 11x Summon.

 

Your Summon Count will not be carried over to other Summons when the Limited Time Pickup Summon ends.
Story Summon and Friend Point Summon are not eligible for the "Guaranteed Summon" feature.
