HitBox Clone Doesnt Change Orienation

local HitBox = Content:WaitForChild('Box'):Clone() --Get HitBox Part From Folder
HitBox.Parent = workspace

HitBox.Position = Character:WaitForChild("HumanoidRootPart").CFrame.lookVector * Vector3.new(0,0,-6)
game:GetService("Debris"):AddItem(HitBox, .75)

Have you tried using CFrame angles?

Example

CFrame.new(Vector3.new(Box.CFrame.X,Box.CFrame.Y,Box.CFrame.Y)) * CFrame.Angles(0,0,-6)

Try change this part :

HitBox.Position = Character:WaitForChild("HumanoidRootPart").CFrame.lookVector * Vector3.new(0,0,-6)

To this :

HitBox.Position = Character:WaitForChild("HumanoidRootPart").CFrame.lookVector * 6
