How to replicate that effect?

  1. What do you want to achieve?

Just want replicate that wind effect:

  1. What is the issue?

Iam not the best with easing styles and directions, so i cant make it very well.

  1. What solutions have you tried so far?

I Tried messy a lot with the values, but no sucess

local tweenService = game:GetService("TweenService")
local mesh = script.Parent

wait(4)

local tween1 = tweenService:Create(mesh,TweenInfo.new(0.1,Enum.EasingStyle.Quad,Enum.EasingDirection.Out),{
	CFrame = (mesh.CFrame * CFrame.new(0,1,0)) * CFrame.Angles(0,math.rad(120),0),
	Size = mesh.Size + Vector3.new(2,2,2),
	Transparency = 0.4
})

local tween2 = tweenService:Create(mesh,TweenInfo.new(0.1,Enum.EasingStyle.Quad,Enum.EasingDirection.Out),{
	CFrame = (mesh.CFrame * CFrame.new(0,2,0)) * CFrame.Angles(0,math.rad(240),0),
	Size = mesh.Size + Vector3.new(4,4,4),
	Transparency = 0.6
})

local tween3 = tweenService:Create(mesh,TweenInfo.new(0.1,Enum.EasingStyle.Quad,Enum.EasingDirection.Out),{
	CFrame = (mesh.CFrame * CFrame.new(0,3,0)) * CFrame.Angles(0,math.rad(360),0),
	Size = mesh.Size + Vector3.new(6,6,6),
	Transparency = 1
})

tween1.Completed:Connect(function()
	tween2:Play()
end)

tween2.Completed:Connect(function()
	tween3:Play()
end)

tween1:Play()

Well, watching the video at 0.5 playback speed, it looks like several things are used to achieve this effect. First, there is an Animation | Roblox Creator Documentation is created for the sword slash, although I guess you could also try tweening the characters Motor6D | Roblox Creator Documentation joints to achieve this as well, although it’d be more difficult. Then it looks like it uses a ParticleEmitter | Roblox Creator Documentation and calls the ParticleEmitter | Roblox Creator Documentation function. I could be wrong, but I think the blue slash effect, blue spiral effect, and the wind spiral are both created using a Beam | Roblox Creator Documentation. I could be wrong though. They could also be created using an invisible part with a SurfaceGui | Roblox Creator Documentation or BillboardGui | Roblox Creator Documentation. However, while I may not be certain about the blue effects, I am near-certain that the wind spiral effect used a Beam.
