How To Make An Aura That A Player Unlocks At A Certain Level/Rebirth?

Hi, I'm trying to make a aura the player gets once they reach a certain lvl or rebirth. I have a ServerScript in StarterCharacterScripts to handle this, the output shows no errors or anything printed as told.

Here is the script:

game.Players.PlayerAdded:Connect(function(player)
    local Aura = game.ReplicatedStorage.Auras.Lightning
    player.CharacterAdded:Connect(function(Char)
        if player.leaderstats.Levels.Value >= 50 and player.leaderstats.Rebirths.Value >= 5 then
            Aura:Clone().Parent = Char.HumanoidRootPart
           print("Given")
        end
    end)
end)
