The so-called "Living Weapons" were actually a kind of golem made by grinding Gemstone Raspberry fruit into dust and mixing it into magic alloy.
Although Gemstone Raspberry fruit looked like "fruit," it was more like a peculiar substance. Even after being ground into dust, it retained its vitality.
In that respect, it bore an obvious resemblance to Prayer Light Fireflies: both retained their spiritual essence and consciousness after changing form.
After Kroya happened to discover this, he immediately wondered whether using the whole fruit as a core had been a little foolish.
The best way to use it was to grind it into dust, then use that dust as a magical material to draw and arrange magic runes inside golems.
That way, the spiritual essence within the raspberries would permeate the entire golem. Perhaps not just the core, but the golem itself could possess intelligence.
He felt this had to be the true use of Gemstone Raspberries. After all, they were magic plants from the Ark Garden. Surely their usefulness could not be so limited?
But after experimenting, Kroya discovered that drawing every magic rune inside an entire golem using Gemstone Raspberry fruit would consume an astronomical quantity of gemstones.
He estimated that several tons of gemstones would be needed to produce the runes for a single golem, and that amount would multiply depending on its complexity.
And that did not even account for the success rate. If he included wastage...
When the Shark Tower Spirit presented that figure to Kroya, he decisively abandoned making large golems.
After a brief consideration, he gave up on that approach and chose another-small golems.
If I can't make large ones, surely I can make small ones? As it happened, he had already made some progress in that area-
The Clockwork Golem.
