Gilded Blackstone

Gilded blackstone is a variant of blackstone that can drop itself or gold nuggets when mined.

Natural generation
Gilded blackstone can generate as part of bastion remnants.

Breaking
Gilded Blackstone requires a pickaxe to be mined, in which case it drops itself or gold nuggets. When mined without a pickaxe, it drops nothing. If Gilded Blackstone is mined with a Silk Touch enchanted pickaxe, it always drops itself. If it's mined with a Fortune III enchanted pickaxe, it always drops gold nuggets.

Block loot
Gilded blackstone has a 90% chance to drop itself when mined with any pickaxe. If it does not drop itself, it will drop 2-5 gold nuggets If mined with Silk Touch, it will always drop itself.

Usage

If it does not drop golden nuggets, it will drop itself as a block. Fortune I increases the chance for this drop to 14.29% ($36/40$), Fortune II increases it to 25%, and Fortune III guarantees the golden nuggets drop.
