How to Participate in the Holy Grail War Trials

The event unfolds as a combat-focused challenge called the Holy Grail War. Here's how it works:

1. Choose a Stage: Select from a list of escalating battle scenarios.

2. Form a Team: Create your ideal composition using synergy and elemental matchups.

3. Defeat Enemies: Win in knockout-style battles to earn Tokens and unlock new stages.

What are “Pieces”?

• After each battle, you earn Tokens, which can be spent on Pieces.
• Pieces act as buffs for your characters.
• Similar Pieces can be merged to unlock class-based effects.
• Stacking compatible Pieces leads to a Bond Effect, which provides powerful bonuses.
• Not satisfied with a Piece? Use the Reset function to refund Tokens and XP fully.

Noble Phantasms and Command Spells

Two powerful tools can turn the tide in the Holy Grail War:

• Noble Phantasms:

            Available in high-difficulty trials, these act like "Curios" with random but powerful effects.                    Some boost damage types like True DMG, while others summon Fate characters into battle.

• Command Spells:

            Unlocked progressively, these spells allow you to enhance your team or gain additional Pieces                mid-run — giving you the tactical edge you need to win.
