ugh. I may fall back on one of my old tricks for this one, time coded magic. That is, do the ritual and energy working, but trap it in a matrix, so it stands as a static working, like a circle or enchantment. Code the release conditions of the enchantment to be the time of the eclipse, tieing in appropriate lunar aspects as necessary so the spell can know when the time is right. Then, it'll release itself when the eclipse is at its summit. Stop by later for any cleanup.
Its kind of like putting a bunch of helium balloons under a net, and then cutting the net away at a later time. The alarm goes off, the net dissolves, the mango is cast, and I get a good night's sleep |
