I’m having a little trouble understanding what could be considered “Spark-Craft” (maybe because English is not my first language).
I assume that it includes every “weird technology” which is not evidently alchemical or arcane: if that is the case, is the Black Salt Bomb missing the “spark-craft” descriptor, just a typo? Are the hull components all inherently “spark-craft” (unless otherwise specified)?
Am I missing something?
On page 209 spark-craft is defined as the combination of a supernatural discipline (spectrology, rituals, alchemy) with technological engineering. I would expect regular explosives to be mundane engineering, but I guess it could be argued that they require alchemy for the explosives and engineering for the casing and detonation method. I’m also confused by all grenades being labeled spark-craft and not the Black Salt Bomb, though. If nothing else, I’m a native english speaker and agree that that is confusing.
It does say a few times in the book that creating a hull is a complex spark-craft project, so yes, any stage of that is spark-craft (I would expect the arcane elements are arcane and spark-craft).
Maybe John Harper can elighten us 🙂
