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

 * Pedguin, one of the few streamers granted early access to Terraria 1.3, discovered that most of the pre-hardmode bosses could be easily defeated, due to the fact that the armor set bonus was previously 75% instead of the current 50%. Cenx, a lead dev, was in a stream watching this happen, so she deemed the bonus overpowered and altered the armor at the last moment before public release. (Confirmed.)
