That would be me...anybody have a fork and knife? I've got some words that need eating.
How it's supposed to help against an Archmage who *should* have protections against this kind of thing, I have no idea. Maybe we'll see some fancy "DnD" type of thing where they don't actually try to scry Masutel, but only the places where he's supposedly been evildoing for the last few years?
The risky part is actually the most obvious to me: they're attempting to scry on an Archmage. To reiterate, they're trying to use magic, relatively uncultivated magic, to spy on a master of the magical arts. Any archmage worth his weight in *dirt* should be able to backtrace a magical scry conducted on his/herself, barring strange rules about how magic works in this world. Or that somehow "lunar" divination is different enough to pass unnoticed, despite being a relatively unobscure form of magic (completely unlike sword-scrying, which is, naturally, completely different from the normal thing). Of course, here I use the word "ought" again, and we can all see the fatal flawed assumption.
Normally this kind of thing doesn't bother me, but you're definately right, this could have been wrapped up a lot easier. Heck, we could have started today's comic with Nimmel and Milov about to perform the divination, and gotten some little dialogue to the effect of:
Milov: "Are you sure you want to go through with this, Nimmel? Attempting to scry on an archmage is going to be dangerous"
Nimmel: "I'm sure. You can count on me."
Milov: "Then let's begin."
