I like that this chapter is basically Conan O'brie'ns favor reaction to a joke. 'Horror... fading into acceptance'. Basically, everytime some dwarf enters the room. 'Oh dread magic... wait that is awesome'.
You mean like spell matrices? This will show up in classes like a week after she writes a paper on it an summits it, with two spells like this I can see her rep being as the mage who makes utility spell that other colleges instantly decide they need their own versions of. In a few decades she is 'Mathilde, you know that mage that inspires all the other colleges to make their own versions of all her original spells'.
I'm bettering long term the dwarfs will have a runic version that can be operated by a journeydwarf to keep them out of trouble mid invasion. Bring in the war table and save brain power for the tactics instead of visualization. If they can make it record things long term they are basically a specialized, runic computer. Only take 2-4 hundred year to get them mainstream.
It is best suited for 3D fighting. Particularly urban and tunnel networks. Anywhere where you have to spend much of your time visualizing the battlefield in complex geography and things can change on a dime. Now the brain power tied up in visualizing it can be subcontracted into brain parts organizing things. It also makes explaining the current situation to people that show up at staggered times so much easier as they can just look for the map and that handles most of the catch up. She already introduced the idea of map markers so you can label key points as well. In a fluid environment like a war room time is lives. Granted its more handy than glorious for surface fighting, but still rather helpful.
So your not going to use it to obliterate an Everchosen directly or anything, but its a massive time saver for command and control uses. Wouldn't be surprized if their is a kitbashed runic version in a week or two of down time.
