Remote.OnServerEvent:Connect(function(player)
    local Character = player.Character
    local Foot = Character.RightFoot
    local Postion = Foot.Position
    local Hitbox = Instance.new("Part",Foot)
    Hitbox.Size = Vector3.new(.2, 15, 15)
    Hitbox.Transparency = 0
    Hitbox.Position = Postion
    Hitbox.Orientation = Vector3.new(0,0, -90)
    Hitbox.BrickColor = BrickColor.new("Really red")
    Hitbox.Anchored = true
    Hitbox.CanCollide = false
    Hitbox.Shape = "Cylinder"
    print("Event Finished")

    Hitbox:Touched(function(hit)
        if not hit.Parent:FindFirstChild("Humanoid") then return end
            if hit.Parent.Name ~= Character.Name then
                hit.Parent:FindFirstChild("Humanoid"):TakeDamge(36)
                wait(2.5)
