Teleportation worked for me. I just had my wizard teleport one of my other characters and that seemed to work just fine. I had tried Cloak and Dagger as well but that didn't seem to work. I think my Wizard's spell reach was a little farther due to the perk I picked so maybe that's it, but the Cloak and Dagger did seem like it would go farther than the images above about using the pyramids.
