Sturdy Fossil

Sturdy Fossils are used to make the Fossil Armor, Bone Throwing Knife, Amber Staff, and Bone Javelin. Sturdy Fossils are made by putting Desert Fossils in the Extractinator, with about a 13.8% chance of acquiring a Sturdy Fossil from one Desert Fossil on average. Sturdy Fossils can also be obtained from Basilisks in Hardmode. It requires at least a Deathbringer Pickaxe or a Nightmare Pickaxe to mine.

Placed Sturdy Fossils sparkle when an ore detecting item is used. Placed Sturdy Fossils also show up when a Metal Detector is used, even though they do not spawn naturally.
