How do I make sure the purchased tool stays within the player's inventory after death?

In my previous question, I asked on how I would make sure a tool will always remain in the player's inventory even after death.

The solution someone gave me was to use :WaitForChild('StarterGear').

This is my shop script, which is a LocalScript in an ImageButton.

script.Parent.MouseEnter:Connect(function()
	game.StarterPlayer.Mouse_hover:Play()
end)

local canPurchase = false

script.Parent.MouseButton1Click:Connect(function()
	game.StarterPlayer.Select:Play()
	local confirmPurchase = script.Parent.Parent.Parent.ConfirmPurchase:Clone()
	confirmPurchase.Visible = true
	confirmPurchase.Parent = script.Parent.Parent.Parent
	confirmPurchase.Yes.MouseButton1Click:Connect(function()
		canPurchase = true
		if game.Players.LocalPlayer:WaitForChild('leaderstats').Vertigo.Value >= 25000 then
			game.StarterPlayer.SFX_SelectAvailable:Play()
			game.Players.LocalPlayer:WaitForChild('leaderstats').Vertigo.Value = game.Players.LocalPlayer:WaitForChild('leaderstats').Vertigo.Value - 10000
			local itemClone = game.ReplicatedStorage.Guns.Sniper:Clone()
			itemClone.Parent = game.Players.LocalPlayer.Backpack
			local itemClone2 = game.ReplicatedStorage.Guns.Sniper:Clone()
			itemClone2.Parent = game.Players.LocalPlayer:WaitForChild('StarterGear')
			game.ReplicatedStorage.Purchased:FireServer(25000)
			confirmPurchase:remove()
			canPurchase = false
		else
			game.ReplicatedStorage.NotEnoughVertigo:FireServer()
		end
	end)
end)

Terribly sorry if it's hard to read, it's the formatting.

Can anyone help me fix this issue? I've had it for a very long time.

I would personally use DataStores for this. DataStores are tables that persist between sessions. To insert/modify data in a DataStore array you must use SetAsync, UpdateAsync and RemoveAsync.

SetAsync creates a new value and modifies it to the parameters specified.

Ex.

local DataStoreService = game:GetService("DataStoreService")
local ExampleStore = DataStoreService:GetDataStore("ExampleData")

ExampleStore:SetAsync("ExamplePlayer", 50)

This creates a new value ExamplePlayer and sets it's corresponding value to 50.

UpdateAsync modifies an existing value to the parameters specified.

Ex.

local DataStoreService = game:GetService("DataStoreService")
local ExampleStore = DataStoreService:GetDataStore("ExampleData")

ExampleStore:UpdateAsync("ExamplePlayer", 50)

This changes ExamplePlayer's corresponding value to 50

RemoveAsync removes a value in the array.

Ex.

local DataStoreService = game:GetService("DataStoreService")
local ExampleStore = DataStoreService:GetDataStore("ExampleData")

ExampleStore:RemoveAsync("ExamplePlayer")

This removes ExamplePlayer and its corresponding value

For more see Data Stores.

Just pop this in ServerScriptService
