Rock Bones

Rock Bones are an easter egg item. Originally a crafting ingredient, it was functionally removed from the mod in 3.2. Its only use is in a chain of item conversions that results in the Experiment W-801.

Like most other easter egg items, Rock Bones do not appear in the creative inventory. They are also unobtainable through /give, as they are instantly deleted when obtained in this manner.

Obtaining
Rock Bones are only obtainable by right-clicking Dark Bones on a Mineralization Station.

Usage
Rock Bones can be right-clicked on an Assassin to obtain a Millennium Upgrader. This has no effect on the Assassin.

When used, the entire stack of Rock Bones will be consumed, but the output will always only be one item, so it is a waste to use more than one at a time.

Trivia

 * Prior to being made into an easter egg item, Rock Bones were a material from the Deeplands dropped by Rockbiters and Cave Creeps (as opposed to being derived from Fleshy Bones, which are dropped by Zal Child). They were used to craft Hazmat Armor, Predatious Armor, and Rockbone Armor.
