trying to make a sword crescent i have to rotate around the player to achieve a slashing effect,
here is how i want it to rotate:

local TweenService = game:GetService('TweenService')

local Slash = workspace.Slash
local DummyHrp = workspace.Characters.Dummy.HumanoidRootPart

local tweenInfo = TweenInfo.new(
	.5,
	Enum.EasingStyle.Quad,
	Enum.EasingDirection.Out
)
local Goal = {
	CFrame = Slash.CFrame * CFrame.Angles(0,math.rad(120),math.rad(-15)),
	Transparency = 0.05
}

task.wait(4)

TweenService:Create(Slash, tweenInfo, Goal):Play()

i tried playing around with these settings but i cant seem to achieve my desired effect, please help
