evictedSaint, Can circuits and gems be used to produce spells by mundane peoples? I am not aware of circuits doing anything more than sustaining a spell that a wizard started...
You are making an insane amount of assumptions based on your own non-canon fluff, RAM.
1.) What?
2.) It's conjuration magic, and we're industrializing it.
3.) When industrializing it, yes.
4.) Conveyors are fluff and easily possible. We already harness mechanical power. To rotate things. If Evicted isn't comfortable with that then he can say we have orphans or something move stuff from circuit to circuit.
5.) If anything, I go too much into fluff. I'm not going to provide detailed explanations of how this application of magic works.
6.) If crystal gets damaged in the field new crystal can be summoned to replace it. Sure, the new crystal is magic-dependent but it's no worse than the rest and can be replaced properly later.
7.) The conveyor isn't a central part at all. The point is we're industrializing and mass-producing crystal instead of having skilled wizards slowly summon exact pieces. I already covered a few of the many possible uses of crystal, we can revise the Crystalworks to add more features, this does not suddenly make everyone forget how to summon crystal, and to be completely honest I don't really get the second half of your point here.
1 magegems are very expensive and still need a wizard to charge them, and they provide very little magical charge. You are talking about mass-scale summoning, magical transferrence, running a steam engine, running who knows how many magical circuits. This won't keep it charged for long enough to make it worth not having a wizard full-time. It is a mistake to include the current-generation mage-gems in this design. It just makes it more expensive with no benefits.
2 It is conjuration magic. Industrialising it means automating the casting of it. We could easily mass-produce this stuff just by running circuits of our existing spells. The whole assembly-line nonsense is just trying to get assembly0line benefits. Assembly0lines have no benefits to conjuration magic because you can skip over all the hassles that make an assembly line benefitious by producing a perfect end-result in a single step. Assembly-lines break up a complex hjob with many steps that all need skills and equipment, and splitting them up into simple jobs that anyone can learn. This is already a single step process, and a simple one at that, once you get over the complexity of applying magic. Breaking it up into smaller steps is just taking away good and adding bad.
3 In all instances, no. You have one device for, what, making a pole? You need to keep it steady the whole way and not over-extend and cut off the axe-head. Our conveyor definitely isn't that precise. If we can get a circuit that repeatedly summons(yet another new complicated thing to research) new blocks then we can make a more complex circuit to repeatedly make a whole axe. If we make a whole axe then we get a working axe. If we do it in parts then we need numerous circuits, all of which need to be aligned with the block or else we have a malformed axe, and the conveyor will not be that precise. We currently have precisely zero spells that change an existing crystal structure. This is not even conjuration at this point. It is a completely new field. Now, maybe, if you wanted to have one thing summon a pol and another summon an axe-head, but then you have to align them properly to get the axe-head to be summoned perfectly around the pole or else it will be wobbly or the summoning will be trying to summon over the top of the pole.
4 find a conveyor from the time and I will believe that they are possible... Woven fabric is all garbage. It will stretch and become unusable almost immediately, and catch on everything. Leather might work, but you need pieces large enough, which means joins, which again means catching on everything, and it will slip when a thick piece meets a thin piece, and leather also stretches, and needs maintenance to keep it flexible. Chain-mail might work. It would catch like crazy but the fact that everything is a concise loop would help, maybe enough. Metal will tend to bend, effectively stretching it though, and a conveyor needs to be tight, and it really needs a pattern for gears to act upon, although chains might work for that too if you don't mind stopping the thing on a regular basis and keeping it very slow. Crystal chains wouldn't bend. Although you might lose links, actually you would almost certaily lose links around the gears. If you could summon the crystals then you could replace the lost links, but relying on the crystalworks that would be impossible. Also, it points out another problem with the crystalworks... I really can't see it working to create chain-mail. Chain-mail is really important if you want flexible crystals without resorting to studding, so that is a pretty big loss if we really want to make use out of the crystals.
5 I almost certainly go too far into fluff, but you make absoultely no effort to explain why this energy would be immune to antimagic, nor why it doesn't want to go back to wherever it came from. You say what is wrong with the old, that our wizards are not allowed to make any permanent enchantments, which bodes poorly for giant birds, but never describe any properties at all for this new energy that swoops in and solves all our problems. If wizard energy is really this completely unique thing, and there is all this other energy around that is just normal and has no restrictions, then let's have our wizards switch to that better energy and not bother with this process at all!
6 We are talking about surface damage and extensive cracking. It is useless to summon more, the whole panel needs to be replaced, that means removing the old before adding the new. And there isn't really any way to remove crystal without damaging any connected crystal without very slowly grinding it away. Replacing worked crystals would be impractical in combat, or at sea...
7 The redundant and dead-end part is that it only applies to crystals. The conveyor is not really relevant because it won't work without better materials and would be inferior even if it did work. We do not need wizards to make complex designs any more than we need wizards to make simple designs. If we can do one with a circuit then we can do the other with a circuit. There is no advantage to simplifying it. We can make a small number of complex circuits, and then blast away with them for all eternity, only replacing them when we have a new design, or we can make a lot of simple circuits, still need to add new ones to make up for the changes in the new designs(unless they are universal manipulators, in which case that is the design we want rather than all this other paraphernalia) and then blast away at them forever. There is no advantage to the latter, and the extra magic needed to make a big thing and then add complexity to it rather than just making the small thing with the complexity pre-installed.
The real point of point seven is that we have cheap metal. The crystal is very similar to metal, and metal actually has some advantages. We want something better than crystal someday, and that would mean overhaulng the crystalworks to take advantage of it, assuming that the crystalworks is even capable of being compatible...
8 It only produces one thing. To make a different thing you need to realign the whole mess all over again. It would be easier to make a completely new large-scale circuit, so you gain nothing here.
9 It is ridiculously complex. Here is a list of new technologies:
Crystal manipulation: We have never altered extant crystals before.
Magical essence transferrence: We have pulled magic out of the air before, and even stored it in compatible receptacles, but that was ll done using purpose-specific materials. This is the unprecedented move of finding a specific enegry in nature, and a specific energy in a material, to which that material's existence is bound, and swapping the two without breaking the spell that was reliant upon the energy.
Mechanisms: The conveyor is right out, no current conveyor would work and making a contemporary one is implausible. We might be able to make something work with clamps and vices? Pulling things around big wheels? We need to keep the things in perfect position and, well, it just wouldn't work. We can do impossible things with magic, this is not magic, it won't work.
Repeat-casting curcuits: Our circuits so far as described as maintenance. There is no indication that I am aware of that they can actually cast spells. It is great as a casting tools, and throw in some mage-gems and they can keep a device running, but actually starting a spell? I believe that we still need wizards for that. Which is why our cannons should still need wizards, they need someone to produce the fireball that triggers it.
Whatever else that I am too worn out to think of... I really doubt that it is just these 4...
