Is magically created food nourishing?
- Yes, as long as it exists. You can live off the food if its duration is long enough, with no bad aftermath.
- No, it isn't nourishing. It can quell hunger, but won't provide sustenance.
- Yes, but leaving you very hungry when the duration ends. Supernaturally hungry, as you must very quickly consume huge amounts of food after a long time on a magical diet.
- Yes, but dropping you dead when the duration ends.
- I don't know.
- Other
Alright, let's settle this once and for all.
This issue has been discussed at length previously. I think the best discussion is on The forgotten Spells thread. Other relevant threads are Creo cheese, and To paradigm or not to paradigm.
There are several issues here:
- What do the RAW say?
- What's the effect on someone that eats (only) magically created foods? Is he nourished?
- What happens when the effect's duration ends? Does he die?
- What about other techniques besides Creo?
The poll is about the second and third point: how nourishing is magically created food ought to be, and what's the effect of stopping such a diet ? But don't answer until you've exhausted the discussion, and am certain of your position.
Of course, the question is only about food NOT created by a momentary Creo ritual. I assume we all agree that food created by a momentary Creo ritual is nourishing and perfectly natural. The argument is about the status of food created with some other Creo spell, or by other (Hermetic) means.
The RAW
The relevant pieces of RAW seem to be
- "...magical food created only nourishes for as long as the duration lasts, and someone who has eaten it becomes extremely hungry when the duration expires." from the Creo guidelines, and
- "Any food created is nutritious only if the creation is a ritual" from the Creo Herbam guidelines, ArM5 p. 136.
Based on these quotes, I think the RAW simply contradicts itself on the matter. A generous interpretation is to read the second passage as "...[permanently] nutritious...", in which case the RAW says the following:
- When someone persists on a diet of magicaly created food, he will be sustained and nourished by it for as long as the food's duration lasts.
- Upon the end of the food's duration, the nutrience derived from such food will be lost, leaving the person extremely hungry. (Not dead.)
But others say my interpretation is wrong. For example,
The Metagame Arguments
Furion eloquently noted on the creo-cheese thread that
I think the key arguments along these lines are as follows:

Gargantua is quite happy. He has gotten Magus Alcofribas Nasier of Jerbiton to fill his larder with enormous quantities of the finest delicacies. In fact, he has spent the greatest part of the last month pigging out in his cellar. Strangely, although he's been eating and eating and eating, he never feels quite full. "So much the better", he exclaims, "that way I still have room for more!"
Sadly, good things never last and the rising full moon brings an end to the feast. Just as he was about to bite in a nice piece of ham, a horrific stomach cramp makes Gargantua wince. When he opens his eyes, the ham is gone, and so are most of the foodstuffs that filled his pantry. Weakened by hunger pangs that refuse to subside, Gargantua crawls towards a barrel which he hope has been spared by this curse that has suddenly befallen him. Luckily for him, the barrel is indeed full, although oats make for a quite miserable fare for one who has grown accustomed to fine ambrosia. Unable to think about anything but food, Gargantua digs in head first.
Two days and three barrels later, he finally stagger out of the cellar, dazed by the amount of food he managed to inhale in such a short time, and substantially wiser about those treacherous devil worshippers that call themselve Hermetic Magi.Magically created food works well to complement real food during a feast, but your grogs aren't going to appreciate being "fed" that way. After the first time you reduce them to devouring their own boots, they are going to be rather suspicious of any food you conjure for them. Expect a loyalty drop.
... my main reason for having a strict view on the non-nourishment of non-ritual food is a matter of setting integrity. I think a ME where someone could make food/nourishment without being dependent on vis would look very very different. A medieval setting is basically a world where there is a narrow divide between prosperity and a year of poor agricultural yeilds resulting in famine and wants. Even in time of prosperity the economics of the covenants would be remarkably different if they could do so. Stories come from limited ressources - in the real world as well as in a fictive world there would be much fever conflicts if there where no limits on ressources. Food isnt just food - it is a vital part in economy, and thus the availability of food also influences what the covenant can use on defenses, buildings, soldiers, specialists, weapons, lab equipment, books - you name it! Limits in ressources make conflicts, add to motivations and underlines many stories - whether in the foreground or not.

See, imo, this whole "no vis, no nourishment" thing is digging a big hole that the above is pointing at. The whole idea is breaking the Medieval Paradigm, if at the same time patching a broken part of the rules.
Something burnt by Magical fire is still burnt after the fire is gone. Something squashed by a magically conjured rock is still squashed after the rock disappears. An item scarred by magical acid, likewise.
So long as the change is enacted by a magically created or altered substance or item, and not affected by magic itself (Muto, Rego), it seems that this holds true.
...
Ergo, items and substances interact "normally" (read "as expected") with magically created items and substances, and retain their last state after that magical item is removed from the equation. (Tho' what happens in the time that follows would be a natural progression from that point onward, re healing, further deterioration, whatever.)
...
Keeping that Paradigm in mind, and how the ME world "sees" things, "water" is pissed out again after a half day or so, so maybe water with any duration longer than 12-24 hours serves its purpose and works just fine to quench thirst.Food is similarly expelled in a day or so, so maybe any food with a duration longer than a couple days is likewise perfectly functional to achieve what we, today, call "nutrition". After it's gone, it's gone - 100% past tense, no metabolism to worry about, no "calorie absorption" or "vitamin intake" or other "long duration" effects. You eat, you crap, the food's done its job, the "nourishment" has already occurred, when do we eat next?
The only question, then, is whether that breaks the game, whether "making food" then becomes far too easy. But, by the Paradigm and the RAW, it strikes me that the above is how it "should" work.
Cuchulainshound you raise some interesting questions in your post - for sake of brevity I haven't included it all.
...
The RAW, with Ravenscroft help and sharp eyes, state explicitly that non-ritual food is not nourishing (p. 77 and p. 136).... I do agree with your argument but I still don’t think it is applicable. I do think it is able to argue the opposite case and still be within ME paradigm.Why? Because the crucial point isn’t whether, within ME paradigm, when, or how humans get nourished by food. Rather it is whether it is within the possibilities of Hermetic Magic. And Hermetic Magic is restricted by the Limit of Energy as well as the Limit of Creation. This might be argued, in-paradigm terms, to be because creation and energy are basically within the realms of the Divine, perhaps on accord of the divinity having created the world and that creation and sustaining life/existence thus being divine forces. Or it might simply be an error in hermetic magic. Therefore it is a general flaw in the kind of magic used by Hermetic magi that makes it impossible for them to create nourishing food. You might say that even though within ME paradigm food would nourish people even if it only exists for a set period before vanishing, the food created by hermetic magic will not. It is sterile, non-fertile, impotent or simply just flawed – whatever word you find fitting. This flaw can only be overcome by using vis in the process. Maybe vis adds that creational force missing, or maybe that is just how Bonisagus patched his theory together.

I'm still in the magically created food is not nutritious and will not sustain life.
It may quell hunger pangs , but you still die.
Part of my reasoning is , if this option is used offensively.You capture someone you want a hold over.
Feed them only on non-vis created food and water ,
and , unless you choose to have real food and water for them ,
they die a horrible death from thirst and starvation in minutes.
(after the duration of the magical food expires)There is no need to limit yourself to one person ,
keep your grogs loyal in this manner ,
it is cheaper than actually feeding them.This option can be used on player characters ,
while some may find it a roleplaying challenge ,
i am not one of them.
I agree. On top of your examples it could also be used to feed some prominent guests, even a sodalis (hmm... think: food spells with a high penetration), and then see them off smiling, knowing very well that they will not go far from your doorstep before they will die a seemingly unvoilent death. I have earlier taken to calling this sillyness for a "horribly cartoonic possibilty of assasination by prolonged exposure to magical created non-permanent food".
Consensus begone!
Phew.
I am currently ambivalent, but I must confess that I'm attracted to Furion's position (although initially I was in favor of my interpretation of the RAW). The possibilities for abuse are simply too great, as Ravenscroft's and Furion's last posts demonstrate.
Other Ideas
The issue of other costs of magical sustenance were raised. That it causes warping seems to be in wide agreement (although I don't think the RAW actually requires that). Another idea that was raised was making aging rolls after the sustenance stops.
The issue of using other techniques was also raised. What happens if you Muto a rock into an apple and eat it? What if you Muto yourself into a cow and eat grass? Can you Muto the need for food out of yourself? Can you Rego someone to provide the effects of sustenance?
I think Mutoing stuff into food works like (non-Ritual) Creo food, but Mutoing yourself into a cow to eat grass can work. Mutoing yourself into rock that doesn't need food works by RAW. Rego cannot be used to heal, provide sustenance, or age someone; probably has something to do with the Divine's monopoly on true creation and life, and with Platonic ideals.
