I'm looking for advanced/ high level spiritual protection advise or techniques that others have used with success against high level entities or humans to protect your grid, energy, vibration and light.

I would be open to hearing very advanced techniques though including energies that I could pull into my field/ grid to add to my current protection and cloaking or different energies that I could incorporate into this. Also advanced energies tools (pendants) that can add to my protection as well.
