An alternate suggestion for a product: have 2 blocks get used to produce 1 slab

Thank you for this. Gives me a practical means to have skilled engravers.

I think it would be very cool to have 'runestone' buildings produced by this. Or at least an additional recipe that makes them in addition to the strict 'training' one.

Very cool. I appreciate why you chose to have just a block output. My initial reaction would be that It would be cool to see it output engraved tablets with quality and have values similar to furniture maybe? Either way, very cool!

I thought about making some kind of engraved block product, but I wanted the reaction to be very simple and not create a lot of products you would have to constantly haul away and stockpile. The only value of this reaction is the training.

But maybe I can look into making another mod (or an update to this) where you can create engraved finished goods, like engraved blocks.

Why not have it take 1 block and produce 1 engraved block as a sort of finished good? Something with ~1.1x value of a plain block or thereabouts.
