To celebrate 19M Downloads of Fate/Grand Order this campaign features new Extra Missions, Login Bonuses, Limited Missions including a new set of Leyline Stones, AP reductions for Main Story and Free Quest First Clears, a new MP Shop CE "Take Romance" and 2x Success Rate for Enchancements. During this Campaign all Ember Gathering and Training Ground nodes will be available every day. Finally the Summoning Banner features limited SSR Caster Murasaki Shikibu and the Craft Essences from the Valentines Event that first introduced her.
Note: While the official news post states that all Free Quests "from Chapter 1 to Chapter 5 (Olympus)" are included in the 1/2 AP Free Quest First Clears, it seems that does infact include Heian-kyo as well.
Note: Events prior to 2023 New Years have not been updated to include all details.
