This is one of the hardest fights in Persona 5, and you will need to be on top of your party management as well as ensure you heal and use buffs throughout the fight. Once you beat The Holy Grail, you get the final boss of the game. Eternal Light: Colossal Almighty damage that will hit your whole party.Gathering Light: Charge for one turn, major damage if you do not guard.

The Holy Grail will add a selection of new attacks during this stage of the battle: While it may not be a hard battle, it can quickly lead to a game over if you are not careful. Keep dealing damage, ensure you guard when the Holy Grail charges up, and heal when your party is injured. As fights in Persona 5 go, this part is rather easy. Once you cut the ability for the Holy Grail to heal, the final stage of this part of the boss fight begins.
