How to Play the Event

Main Quests in the Limited Time Event "Grail Front - Castle of Shining Dawn, Castle of Shadowed Dusk" will be unlocked on a daily schedule.
In addition to battling in Grail Fronts as you progress in the Main Story, Free Quests where you can collect event items will unlock.

This Grail Front has an event map, unlike previous Grail Fronts!
Move around the event map to investigate the Singularity and take on Grail Fronts to see the story unfold.

Depending on the Quests You Choose, the Event Map Will Change to Day or Night!

In this event, the event map will change to "Day" or "Night" depending on your choices in the Main Story.
The difficulty and contents of each Grail Front will also change depending on if it is Day or Night.

Additionally, once you clear a certain quest in the Main Story, you will be able to change the event map's time of day whenever you'd like.
You can battle in each Grail Front as many times as you'd like, so change the time of day on the event map and enjoy battling in the Grail Fronts that differ from the first time you took them on.

The victory conditions for Grail Fronts until now have been "defeat the enemy Master" or "defeat all enemies". However, from this Grail Front, new victory conditions such as "reach the Suppression Point" and "defeat a certain enemy" have been added.
In some cases, the victory conditions will change when you fulfill certain requirements while progressing through a Grail Front.

You can check the victory conditions by tapping "Rules" at the bottom left of the screen.

In this Grail Front, Servants will have conversations while on the Grail Front map. They'll also give some useful information to help you win, so you won't want to miss these!

If you are defeated in a Grail Front battle, you can Continue by using three Command Spells or one Saint Quartz.
If you Continue, your ally Servants and Master will return to their original positions on the map with their HP fully restored and NP Gauge charged to 100%.
You can resume the battle just how it was before using Continue—enemies you'd damaged or defeated, as well as treasure chests you'd acquired, will remain the same—so take advantage of the favorable situation and aim for victory!

Walls on the Grail Front map can be destroyed by attacks from Masters and Servants. The amount of actions consumed when attacking walls varies by class. Your Master will also need to spend a certain amount of actions.

By destroying walls, you will be able to advance to spaces on the map that you couldn't reach before. Open up new routes to advance and gain an advantage in battle!
