Chiseled is a WIP port of the chisel mod for 1.16.5. It so far only includes stone variations and the factory and science blocks

While this mod is still WIP it already adds a nice variety of existing blocks and the ever so loved factory blocks which I feel like is enough to justify it being added in the pack and if not now at least in the foreseeable future.

We'll consider it, I am however against adding it because it's almost an exact copy of Chisel, which is being ported afaik.

It's gonna be a no, it seems a tad unstable, and I'd rather wait out for the original Chisel mod.
If Chiseled at some point obtains written permission from the maintainer or Chisel I will reconsider.
