How can I make the sword ability only play when being damaged?

I am revamping a SFOTH sword, which Is the GhostWalker but what I like to call It: "Ghost Eye" The ability Is to make you completely Invisible when taking damage, but after 5 seconds or when the tool has been equip It makes you slightly Invisible, the tool works but I realized that when taking damage or healing It still fires the ability

Script:

local Tool = script.Parent
local SoundFolder = Tool.Sounds
local SlashAttack
local Boolens = {
    Debounce = false,
    CanDamage = false
}
local Animations = { ---Oh boi there Is alot
    EquipAnimation = Tool.EquipAnimation,
    Idle = Tool.Idle,
    Slash = Tool.Slash
}

Tool.Equipped:Connect(function()
    SoundFolder.Unsheath:Play()
    local Humanoid = Tool.Parent.Humanoid
    Humanoid.WalkSpeed = 20
    Tool.Handle.Transparency = 0.9
    Humanoid.Parent.Head.Transparency = 0.9
    Humanoid.Parent.Torso.Transparency = 0.9
    Humanoid.Parent["Left Arm"].Transparency = 0.9
    Humanoid.Parent["Right Arm"].Transparency = 0.9
    Humanoid.Parent["Left Leg"].Transparency = 0.9
    Humanoid.Parent["Right Leg"].Transparency = 0.9

    local EquipAnimationTrack = Humanoid:FindFirstChild("Animator"):LoadAnimation(Animations.EquipAnimation)
    EquipAnimationTrack:Play()
    task.wait(0.30)
    local Idle = Humanoid:FindFirstChild("Animator"):LoadAnimation(Animations.Idle)
    Idle:Play()
    Humanoid.HealthChange:Connect(function()
        Humanoid.WalkSpeed = 30
        Tool.Handle.Transparency = 1
        Humanoid.Parent.Head.Transparency = 1
        Humanoid.Parent.Torso.Transparency = 1
        Humanoid.Parent["Left Arm"].Transparency = 1
        Humanoid.Parent["Right Arm"].Transparency = 1
        Humanoid.Parent["Left Leg"].Transparency = 1
        Humanoid.Parent["Right Leg"].Transparency = 1
        wait(5)Humanoid.WalkSpeed = 20

        Humanoid.Parent["Left Leg"].Transparency = 0.9

        Humanoid.Parent["Left Leg"].Transparency = 0
        Humanoid.Parent["Right Leg"].Transparency = 0
        Idle:Stop()
    end)
end)

Originally made you Invisible when damaged, even the original tooltip tells you this:
A ghost with algophobia formed Into a sword, thats why It makes you Invisible when being damaged
