Why does my fire spell still work after unequipping the wand?

I'm trying to make it where a fire spell only works if you have the wand equipped on your hand. However, after equipping and then unequipping, you still can use the fire spell. Does anyone have a fix for this?

Local Script

local UIS = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local mouse = player:GetMouse()
local debounce = false

script.Parent.Equipped:Connect(function(player)
	UIS.InputBegan:Connect(function(Input, IsTyping)
		if not IsTyping then
			if not debounce then
				debounce = true
				
				if Input.KeyCode == Enum.KeyCode.Z then
					game.ReplicatedStorage.Fireball:FireServer(mouse.Hit.Position)
				end
				
				wait(0.1)
				debounce = false		
			end
		end
	end)
end)

Script

local fireball = game.ServerStorage:WaitForChild("Fireball")
script.Parent.Equipped:Connect(function()
	game.ReplicatedStorage.Fireball.OnServerEvent:Connect(function(player, mousePos)
		
		local character = player.Character
		local newFireball = fireball:Clone()
			
		newFireball.Position = character.HumanoidRootPart.Position
		newFireball.Parent = workspace
		local velocity = Instance.new("BodyVelocity", newFireball)
		velocity.Velocity = CFrame.new(newFireball.Position, mousePos).LookVector * 100
		velocity.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
			
		local touchConn
		
		touchConn = newFireball.Touched:Connect(function(hit)
			if hit == nil then return end
			if hit.Parent.Name == player.Name then return end
			if hit.Parent:FindFirstChild("Humanoid") then
				hit.Parent:FindFirstChild("Humanoid"):TakeDamage(20)
				if touchConn ~= nil then touchConn:Disconnect() end
				newFireball:Destroy()
				
			end
		end)
		
		wait(2)
		
		if touchConn ~= nil then touchConn:Disconnect() end
		newFireball:Destroy()
	end)
end)
