In this video I will show you how to unlock the Saber Alter F Move in Sailor Piece.

To unlock the Saber Alter F Move, you must first obtain the Saber Alter Fighting Style. After that, you need several materials including Corruption Core, Alter Clan, and Dark Grail.

Corruption Core can be obtained by defeating the Saber Alter Boss, Alter Clan can be obtained through Clan Reroll, and Dark Grail can be dropped by defeating NPCs in the game.

Once you collect all the required items, go to Boss Island and talk to the Saber Alter F Move Mastery NPC. She will unlock the F Move and give you a 30% damage buff.
