Fossil armor

The Fossil Armor is a pre-Hardmode armor. It has a lower class amount of defense, but increases thrown item velocity and damage significantly. In addition, wearing the full set grants a 50% chance to not consume thrown items (this does not include bombs and dynamite). This makes Fossil Armor great for using Bone Javelins, Bone Throwing Knives, and other thrown weapons. The Fossil Armor set is made using Sturdy Fossils, which have a chance to be dropped from putting Desert Fossils in the Extractinator.

Trivia

 * In the early access release of Terraria 1.3, the armor's set bonus was 75% chance to not consume thrown items. It was reduced to 50% before the public release.
