Applied Magic: Armoury
Something that had occurred to me recently is the use of Spells from Magic to produce non-magical goods. In particular the Shape Metal Spell offers capabilities that even TL8 is only starting to verge upon.
For example, if the Shape Metal spell was known in Camelot they actually could have the anachronistic plate armor seen in the movies. Easily custom fitted to each Knight too. However, What about chain? The Shape Metal Spell does say it works on liquid metal and shaped metal retains the shape it was put in without special concentration as long as the Spell is maintained. Large bits of metal shaped this way would take an annoying amount of time to cool into solidity but what about wire suitable for making chain armor? You have your crucible full of liquid steel (whihc you can make with Heat or Fast fire)and you use Shape Metal to draw a narrow stream of liquid metal that's the right thickness for the wire that's right for chain armor. You can even turn the liquid metal into interlocked links that should cool into solidity in the minute long Duration of the Spell. So you've not only bypassed the conventional drawing of metal into wire but the ends of your chain links don't need to be riveted together either. It prbably does need a Specilaized Skill or Technique to maically "knit" chain armor swiftly and efficiently this way but it only takes Magery 1 and the prereq chain isn't very long. That's not bad for doing away with the mundane armoury's annoying parts. So, would you give this "shaped" chain armor another +1 DR? To my understanding if a link fails when stressed (such as in a hard thrust) it's most likely to fail at the rivet. Uniform strength all through the link would seem to amke it less likely to fail.

Re: Applied Magic: Armoury
Shape Metal is quite unclear about how fine control it grants, but there's always Reshape. However, welds are quite capable of being stronger than the material being welded (modern mail can also make half the rings out of stamped metal with no gaps, but I don't think there's historical examples).

Re: Applied Magic: Armoury
The vast majority of Western European mail from the Roman period to the 14th C was made of half riveted and half solid (punched) links - not because it is stronger, but because the mail is faster to assemble. When properly-riveted links are stressed, they tend to fail along the wire, not at the join, so there is a negligible difference in strength between punched, welded, and riveted links.

Another consideration - a common "stage magic" trick is to take two seemingly-whole metal rings and bang them together such that they become linked. There may be a spell to accomplish this directly with actually-whole metal rings, and repurposing that here would let you simply use punched rings and link them together.

Re: Applied Magic: Armoury
Historically, the bloomsmith took the bloom from the smelter and hammered it into billets. Some of these billets were sold to the wire-drawers and plateners to be turned into wire and plate. These were then sold to link-makers to be turned into links and rivets. These were sold to the mailleurs who would weave the links into sheets of mail. The mail sheets were sold to the armourers (who also bought loose links and rivets from the link-makers) to be tailored into armour. The Romans had large fabricas where all of these processes (except for the bloomsmithing) were done at the same location.
You could use simple spells for each of these processes except for the last one.

One way to keep Shape Metal from being too much of a substitute for mundane skills is to require a successful craft skill to make whatever it is you're trying to make using Shape Metal. A failed roll means that you get something that looks sort of like what you were trying to create but which includes flaws. For example, if you're trying to shape a chunk of iron into a knife, roll against Armoury (Melee Weapons) to get anything better than a Cheap-Quality knife-shaped object as opposed to a blade you'd trust your life with. Further enchantments might not be possible for items which aren't at least Good-Quality regardless of how they're created. The exception might be if the mage effectively acts as an assistant to someone who knows what they're doing. In that case, the mage just shapes the metal so that it's the right general size and shape, gives it the softness of lead or gold and "commands" the metal to move in reaction to the craftsman's actions. In itself, that would make a smith far more efficient, since they don't have to mess with tending the forge, heating or quenching work in progress to deal with changes to the metal as it's being worked or grasping a piece of metal with tongs to hot-work it. The smith would also spend far less time hammering the metal to get it to move the way they want it to and might even be able to stretch or bend metal billets by hand, as if they were taffy. The last trick would be extremely useful when doing final fitting of plate armor. As a guess, a Shape Metal enchantment or an assistant who knows that spell would result in a 100% savings in fuel (not an insignificant cost) and perhaps 25% to 200% increase in efficiency depending on what you're making. Fiddly work like mail would see the biggest efficiency boost, since you could just turn a billet of metal into a coil of wire, get the coil to bend and "pinch off" solid links and then link the solid rings rather than messing with riveting. |

I probably wouldn't be as generous as you outlined with Shape by itself. It was just that simple metal shapes were more applicable to armor than weapons. Shaping plates that made good armor would definitely need Armoury skill. you're just bypassing a lot of hammer work. Shape Plates might default to basic Armoury but Make Rivetlless Mail would be a Technique at a significant penalty from Armoury. Also, if you Shape solid wire into a loop I think you might only have butted mail instead of rivetless links. That's why I was wanting to work with molten metal. That should come together seamlessly and homogenously. You probably do need to work quickly before it cools into solidity.It might be the best way to make links without stressing the metal though. An odd benefit to rivetless mail is that the rivets in regular mail tend to make small scratches on smooth surfaces or to catch at threads in fabric. The knight's surcoat was partly to help prevent that.

Re: Applied Magic: Armoury
You can't weld mail links by smacking the links on an anvil; the anvil sucks out the heat too quickly. The best way is to hold the link in a furnace while pressing the join with tongs. You don't need to melt the metal to weld a join, it just needs to be brought up to a yellow heat.
We have a couple of sources telling us that the surcoat was intended to protect the armour from rain. Mail has sharp edges when it is first made but abrasion smooths everything out after wearing it for a while. Mail was cleaned by rolling it in a barrel with materials such as bran or sawdust. If this was done just after manufacturing, it would smooth off any jagged edges.

Re: Applied Magic: Armoury
No doubt Shape Metal would make the creation of armor far, far faster, especially when it came to making mail. Having seen how laborious it is just to take modern-day steel wire and cut/shape it into rings, I'd say it wasn't so much a matter of increasing efficiency 25-200% as fivefold at the least.
But I'm not sold at all on it having more DR. That's talking Shape adding what, 20% to its protective value? I just don't see that.
