Trying To Make ToolSave Not Dupe Tools AND Making Tool Check?

The Title Is Confusing IK Buuuutt i will try to explain it

The First Script im making is a script to save tools and when you reset it duplicates the basic starter tool, so i want it to not dupe and i have tried an IF statement shown here:

char.Humanoid.Died:connect(function()
            char.Humanoid:UnequipTools()
            if player.Backpack:WaitForChild("Basic Halo") == true
            then
                print("Already Has Basic")
                else
        local old = player.StarterGear:GetChildren()
        for i = 1, #old do
            old[i]:Destroy()
        end

        local new = player.Backpack:GetChildren()
        for i = 1, #new do
            new[i].Parent = player.StarterGear
        end     
            end 
            end)    

Second Script: the second one is a local script to check if the player has the Molten Halo Tool when joining if the player does it will not give them the starter halo....

ToolSave Script (Normal Script, Server Script Service)

local ds = game:GetService("DataStoreService")
local store = ds:GetDataStore("saveStore")
local library = game:GetService("ServerStorage").ShopItems

--< directory functions

local dir = {}

local function edit(player, list)
    dir[player.Name] = list
end

local function setup(player, list)
    for i = 1, #list do
        local tool = library:FindFirstChild(list[i])
        if tool then
            local clone = tool:Clone()
            clone.Parent = player.Backpack
        else
            print(list[i] .. " not found")
        end
    end
end

--< player events

game.Players.PlayerAdded:connect(function(player)

local ready = false

    player.CharacterAdded:connect(function(char)

    local bp = player.Backpack
    local data = nil

    if ready == false then
        ready = true

        data = store:GetAsync(player.UserId)

        if data then
            setup(player, data)
            edit(player, data)
        end
    end 

    char.Humanoid.Died:connect(function()
            char.Humanoid:UnequipTools()
            if player.Backpack:WaitForChild("Basic Halo") == true
            then
                print("Already Has Basic")
                else
        local old = player.StarterGear:GetChildren()
        for i = 1, #old do
            old[i]:Destroy()
        end

        local new = player.Backpack:GetChildren()
        for i = 1, #new do
            new[i].Parent = player.StarterGear
        end     
            end 
            end)    


    --< adjuster

    local count = 0

    local function adjust()

    if char.Humanoid.Health > 0 then

        local list = {}

        local equipped = char:FindFirstChildOfClass("Tool")
        if equipped then
            table.insert(list, equipped.Name)
        end 

        local tools = bp:GetChildren()
        for i = 1, #tools do
            table.insert(list, tools[i].Name)
        end

        if count ~= #list then
            edit(player, list)
            count = #list
        end
    end
    end

    --< child events

    bp.ChildAdded:connect(adjust)   
    bp.ChildRemoved:connect(adjust) 

    char.ChildAdded:connect(function(child)
        if child.ClassName == "Tool" then
            adjust()
        end
    end)

    char.ChildRemoved:connect(function(child)
        if child.ClassName == "Tool" then
            adjust()
        end
    end)    

    end)
end)

game.Players.PlayerRemoving:connect(function(player)
    store:SetAsync(player.UserId, dir[player.Name])
    dir[player.Name] = nil
end)

--< safety

game:BindToClose(function()
    wait(5)
end)

--[[ Shiro75 ]]--

the local script to check if the player has the tool:

local player = game.Players.LocalPlayer

function checkBasic()
    wait(0.6)
    if player.Backpack:GetFirstChild("Molten Halo") == true
        then
        player.Backpack:GetFirstChild("Basic Halo"):Destroy()
        end 
    end

game.Players.ChildAdded:Connect(checkBasic)

Thanks Joe.
