Ability does not disappear when player dies?

So when a player dies then uses the ability, it stays there forever. Both scripts are inside the tool

--Server Script--
local tween = game:GetService("TweenService")
local casting = false

script.Parent.RemoteEvent.OnServerEvent:Connect(function(player)
	if casting == true then return end
	casting = true
	
	local iceSpikes = game.ReplicatedStorage.LightCage:Clone()
	local dmg = 3
	--Pre position
	iceSpikes:SetPrimaryPartCFrame(player.Character.HumanoidRootPart.CFrame)
	iceSpikes.Parent = workspace
	local endPositions = {Position = {}, Orientation = {}}
	for i,v in pairs(iceSpikes.Spikes:GetChildren()) do
		endPositions["Position"][i] = v.Position
		endPositions["Orientation"][i] = v.Orientation
		v.CFrame = CFrame.new(iceSpikes.Center.Position)
	end
	
	--Activate
	wait(0)
	local Sound = script.Parent.Lightning
	Sound:Play()
	for i,v in pairs(iceSpikes.Spikes:GetChildren()) do
		v.Orientation = endPositions["Orientation"][i]
		tween:Create(v, TweenInfo.new(0), {Position = endPositions["Position"][i]}):Play()
	end
	
	--Attack
	for i,v in pairs(iceSpikes.Spikes:GetChildren()) do
		v.Touched:Connect(function(hit)
			if hit.Parent:FindFirstChild("Humanoid") and not hit.Parent:FindFirstChild("AlreadyHit") and not hit:IsDescendantOf(player.Character) then --Check if its a player
				local enemyHumanoid = hit.Parent:FindFirstChild("Humanoid")
				enemyHumanoid:TakeDamage(dmg)
			end
		end)
	end
	
	--Remove
	wait(5)
	Sound:Stop()
	iceSpikes:Destroy()
	casting = false
	wait(2)
	if iceSpikes.Parent == workspace then
		iceSpikes:Destroy()
	end
end)

--Local Script--
local tool = script.Parent

tool.Activated:Connect(function()
script.Parent.RemoteEvent:FireServer()
end)

The problem is that the script is located inside the tool. When a players character dies, the tool and its descendants are also destroyed. This prevents the script from continuing.

To fix this, simply place the RemoteEvent in ReplicatedStorage, and have the ServerScript in ServerScriptService. Since the script is not inside of a tool, it will not be removed, thus it will continue, even if the players character dies.

Why have the same serverscript replicated to each tool, when it can all be controlled through just one? Having just one will also keep the lag to a minimum.
