Design: Functional Anti-Magic Charms [1, 5, 5]
Well...it turns out we didn't really need diamonds, after all. The King was very happy to have the ones in his crown back.
Quartz works just as well, so long as the crystalline structure is pure enough. This is a fantastic development, as it means we can produce enough to give one to each squad to warn of casting being done on them in secret. This means our guards will get a warning if the enemy tries to lull them to sleep, or indeed try anything else that generates a magical field in their presence.
It still doesn't...quite...stop magic. Not yet, at least. They get too hot to hold, which means they ARE absorbing some magical energy from the air, but it's all lost to heat. There seems to be some mathematical relation between the energy produced and the magical field generated, but how we can increase the absorption enough to actively pull it from the air is beyond our understanding at the moment. The new math Jibril Saadiya developed - "Calculus" - is gaining some positive attention from our researchers as it seems to have more applications to the field of magic than initially thought. It's still an entirely useless method of math outside of magic applications, but it does explain a few phenomenon in our research. Jibril Saadiya argues that he just needs more time researching Anti-Magic charms before he can get them working. Our other researchers are skeptical that it's possible to do, but he is adamant that the math supports the concept. Expensive
