Fossil armor

Fossil armor is a pre-Hardmode armor set consisting of the Fossil Helmet, Fossil Plate, and Fossil Greaves. It has notably less defense than most other similarly available armor sets, providing a total of defense.

On the, the Helmet and Greaves increase ranged critical strike chance by 4% per each, with the Plate increasing ranged damage by 5%, and wearing the full set grants a 20% chance to not consume ammo, making Fossil armor great for using the Minishark as well as other early-game guns such as the Flintlock Pistol or The Undertaker, and also bows.

On the, Fossil armor instead greatly increases the velocity, damage, and critical strike chance of throwing weapons, and wearing the full set grants a 50% chance to not consume thrown items (not including ), making Fossil armor great for using Bone Javelins, Bone Throwing Knives, and other throwing weapons.

The Fossil armor set is made using 60 /  75 Sturdy Fossils, which have a 10% chance to be dropped from the Extractinator when Desert Fossils are inserted.

Tips

 * The 3% boost to ranged critical strike chance on each piece is actually the same as the Ninja Armor's individual armor pieces. The Ninja set has 1 extra defense and boosts the crit chance of all damage types, not just Ranged. If ammo consumption isn't an issue, the set bonus of increased movement speed could be more useful as well.

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.
 * This is the only pre-Hardmode armor set in which the helmet sells for less than the rest of the pieces.
