Note that Free Quests that already have been cleared will no longer be a part of the half AP campaign.

Part 2

[Official Class Pickup Summon (Daily) Campaign] News Link!
The Daily Pickup Summon is available to all Masters regardless of story progression!
A different Servant class is available each day following the below schedule. During each day, only Servants of the Pickup Class can be summoned. Craft Essences are unchanged and can also be summoned.
Predicted rates for each of the Servants are listed below. Always make sure to check the "Summon Info" for accurate summoning odds!

Important Notes regarding Class Banners:

Class banners are special banners in which there are no rate-ups at all, but the roster itself is limited. As a result, the summoning odds are very different from normal.
Instead of a rate up, the overall summoning percentage is divided across every normal + story Servant of that rarity.
This is the first proper Rate-Up for Rider of Resistance!
Three Servants in particular will have higher summoning rates than normal: Bedivere will have a strong rate-up at a stunning 10% to get a copy, Rider of Resistance will have a decent (double the usual 3* rate) 8% chance to get a copy, while Jaguar Warrior has an increased Summon rate of 6.67%.
Note that Jaguar Warrior will have a reduced rate-up in future class banners due to the appearance of (non-story locked) Lancer of Purgatorio.
For comparison: normal rate-ups for 3* Servants are 4%.
Class banners are excellent for filling up a class imbalance in your roster, but naturally targeting a specific higher rarity Servant isn't as feasible.
