Table talk (Bibracte)

My understanding is that the +3 levels of size increase is to cover the smallest coherent boundary both inside and out of the regio. What would this "normal" sized option cover?

I was also considering an armageddon scenario. In which cases, you want as many people as possible to flee. So a lower magnitude spell that transports everyone to a specially-prepared defensive location allows us to save more people. Putting them in keepsakes which covenant members carry, rather than statues, means that we can save divergent groups even if they get isolated, and the transportation will be wherever people already are.

Oh. Or you could make Greater Invested Device/Statues which only accept mental commands, but offer unlimited uses. Or instead of mental commands, you could make them emotional triggers! A teleportation device which only works on people who are truly afraid!

"Well, I concede that a general strategy of Rego-based defenses makes sense, given our aura, and it hadn't occurred to me that the spell would linger. That is certainly a point in its favor. On the other hand, it's not the cadre of grogs that worry me so much -- we do a generally good job of keeping them on our side, but the cadre of items lying around that worry me. Our Mentem sources are strong enough that it might be worthwhile to restrict our items to mental command only. But that increases the time and cost of those items measurably.

"It would be far cheaper if we restricted such items in certain other ways. For example, if we branded those we trust to use the items with a secret sigil, then it would be much cheaper to detect the existence of such a brand and limit usage to that group. However, that effectively gives permanent access, and would use Corpus or Intellego, neither of which we have in quantities worth considering.

We should use the materials we have in greatest supply for our defenses -- the chess pieces. The Rego Terram vis is plentiful and powerful. We effectively double the attack capacity of those wielding items made from it."

"You over-complicate things. You just need somewhere to store the elemental and a device that summons and banishes it."

You'd still be grabbing everyone in the building, including any enemies.
