Core-Blasted Stone

Core-Blasted Stones are objects found in Exodor. These were added bit after Exodor release, same time as Exodor Cryptograms treasure hunt.

You could use randomly dropped Core-Blasted Stone Breakers on stone to get Core-Blasted Shards, which are tokens from Cryptograms content for various materials. It's likely Stone Breakers were removed too on patch v102 in January 2021.
