It would work with mark of time and gravity pendulums too, I think. To be honest, I don't think that it really matters because you will gather enough time quanta by the end of the game to keep bouncing that little photon you have. Also, 6 pendulums = 6 time quanta every other turn, which equals 3 every turn.. You shouldn't fear running out of quanta.
By the way, even if the small scarabs hit you, the Pharaohs won't be able to, and that little damage reduction helps too.
