Should have gone for the pulse-jets, it is some complex magic combination if you build it from crystals, which is ideal because they have no effective wear-and-tear, but the principal problem of the thing is a controllable explosion. Also the question of why you would do such a thing, I mean, propelling things out of tubes is pretty odd thinking unless you have seen fireworks... But if you start with a controllable explosion, and see it blowing things around, the pulse-jet is actually a pretty logical progression aside from some minor details that ought be solved with trial-and-error in short order given their nature. Like, we tried putting a fireball behind the boat, but if we get it off by a little then it just rocks it to the side, if only we could force it to push the boat forwards, hmm, some sort of tube maybe? Then it would always be in the right place... We find that it pushes the boat forwards then pulls it back again, we noticed the vapour being sucked back in, we need to block it somehow. The cork was pulled in magnificently, but the fireball was much weaker and the cork was destroyed and it was just waiting to suck again as soon as the cork was removed, actually continuously sucking on it... Well, lets let air in the front instead of the back, and we will block it when we detonate it. The stopper keeps getting blown out, we need to block it somehow, wait! if we did that, it would close all by itself when it pushed back! just need to stop it falling off when air is sucked in the front... Hey, we could do the same thing at the back except in reverse to stop it sucking between explosions...
Jets may seem more technological than steam, but in practise, given what we have, it is much simpler...
So, we can work on steam again and risk getting nothing this turn, work on steam baby-steps and get something simple, like a national effort metal stamper than can reduce the cost of one of our equipments at the cost of Myark's time, or do something different and delay steam-tech but hopefully get something out this turn...
Steam just works now
We wanna reroll our steam pliz!
Low-power engine
Reducing the size and power of the engine has advantages in terms of low magic use and easier material reinforcement along with smaller explosions if things go wrong. We can just pipe the steam into the ocean for a small increase in thrust and experiment with steam-powered oars mounted on wheels. These small steam-engines are very weak compared to a longship, but they give us a chance to learn more about the technology.
Steam-press
We work on getting our engine to work as-is. Hook it up to a low-geared wheel that rolls patterns onto metal sheets to produce plate-armour more quickly.
Steam-lumbermill
We work on getting our engine to work as-is. Hook it up to some sort of circular saw-like mechanism and carve up wooden beams like nobody's business. More Longships!!!
Magic immune crystals
We produce a reduced-scale antimagic charm that affixes to a crystal weapon and only covers the weapon to make it immune to our enemies' magic, allowing us to reintroduce some of our crystal weapons in smaller quantities.
antimagic arrows
We revise our antimagic to fit onto some of our anti-wizard guard's arrows, using the old burst-into-flames variant. Effectively a revision of the guard, but theoretically a revision of the charms...
