So whenever i use the script in game on the dev console game.ReplicatedStorage.FolderChange:FireServer("llBreezyll", "DevilFruit", "Flame") it says unable to cast value to object
Try using:
(llBreezyll MUST be in the game with you other wise it will error.)
game.ReplicatedStorage.FolderChange:FireServer(game.Players.llBreezyll.Name, "DevilFruit", "Flame")
Please accept this answer if it helped!
