You are a mind-boggingly-powerful archmagus: while you master no strange mysteries or exotic magics, you can spontaneously cast, without fatigue, any tenth magnitude hermetic spell. But you are terrible at cooking, whether through the Arts or by mundane means. Fortunately, your covenant employs one of the best cooks in Mythic Europe; unfortunately, a hundred leagues of terrible hazards lie between you and your covenant, and a powerful Geas prevents you from returning there tonight or in fact moving from where you are.
Now, you do have an arcane connection to said cook, and ReCo magics make it easy to fetch her for the evening, and then send her back. But you've pulled off this trick (and others!) one-too-many times, and you'd like to avoid any more warping of the poor lass lest her cooking skills end up mystically impaired.
So the problem is rather simple: can you fetch the cook and send her back without warping her, using your spontaneous magic? Read one solution here.
I would probably send them a platter that I have an Arcane connection to, have them make my food and put it on the platter, and then use the Arcane connection to summon the platter, with requisites, back to me.
If I can spontaneously cast any 10th magnitude (level 50) hermetic spell i would think I could simply teleport a conveyance to her and then teleport it back. the most obvious would be something like a cart or horse, but even a large cauldron would work in a pinch.
Apparently that does not work (see TME p.107): living beings are not teleported along with the main target of the teleport (with the exceptions of familiars etc.). So if you teleport a cauldron to her, and teleport the cauldron back ... you still get only the cauldron.
It would work with really really fast transportation that actually crossed the intervening space. Teleport a cauldron to the cook and fly it back, however quickly, with the cook being dragged along without ever being directly affected by the magic. But that would mean dragging her through "a hundred leagues of terrible hazards" (and another hundred on the return trip) ... and that would likely scar the poor lass even more than a warping point or two.
Bah, spoilsport. (I take it over the terrible hazards is not an option, even with invisibility?)
On a more serious attempt, I did consider turning her briefly into fire, on the basis that you can do a Touch version of Seven League Stride for that at level 25, but sadly I have so far failed to come up with a way to turn her into fire that does not involved her either being warped from that or very injured.
Open an arcane tunnel.
Turn the cook into a land animal
Turn the land animal into a plant
Summon the plant.
Dispel your stupid ongoing effects.
Remind the cook he's there to cook, not to complain about how weird you are, with a healthy dose of Mentem.
Duck the storyteller's book being thrown accross the room.
As far as I can tell (TME p.107) summoning (i.e. teleporting) a plant 5 feet is base 10, so teleporting a plant other than yourself beyond 7 leagues is Base 10 + 5 magnitudes for unlimited distance + 1 Touch = ReHe40. That warps!
Does a Fire count as a non-living item for the purpose of the Base 15 MuAn guideline "change an Animal into a non-living item"? If so, I think you can do it that way.
It's technically "item" rather than object (I realised on a reread, but clearly didn't get in with the edit before you saw the post), but I'm not sure that helps much. Sadly I can't see a specific MuAn(Ig) guideline.
