Most versatile TeFo for a spont specialist?

My apologies. I missed the base effect affect +2 magnitude spell in the Rego Vim guidelines, so I was making everything 2 magnitudes harder. So with sponts, 20 and 30 casting total after roll, to spont the level 5 and 10 for sun duration. 30 and 40 for moon. 30 is achievable at gauntlet without being incredibly narrow focused, 40 is a very narrow focus.

i dont follow at all, you dont need a custom version of the evil eye for every spell you want to cast through it. theres no reason to make 1 of each of these items, total 4, and the supression and container versions are solidly nice-to-haves rather than strictly useful

A single ReVi tunnel spell can be used for any spells you want to send through it so much as their levels aren’t too high for the tunnel and the tunnel lasts long enough to cast them all.

So think so many people until they see them in action. These are probably two of the three most useful spells in the entire game. They’re not useful on their own in the absence of other magic. But given that you can cast other spells, they are so incredibly powerful, the maintenance spell being the only stronger one. Those three together are the top three.
