Necro armor

Necro armor is a post-Skeletron armor set consisting of the Necro Helmet, Necro Breastplate, and Necro Greaves. Crafting a full set requires a total of 135 Cobwebs and 150 Bones.

The Ancient Necro Helmet is a rare drop from Angry Bones and Dark Casters in the Dungeon, with a chance of dropping. On the, it is functionally identical to the Necro Helmet and the two helmets are interchangeable with no bonus loss.

A full set grants a basic 19 /  16 defense and  10% /  15% increased ranged critical strike chance /  20% chance not to consume ammo. In addition, each piece increases ranged damage by 5%, increasing ranged damage by a total of 15%. It is currently one of only two ranged-specific pre-Hardmode armor sets on, the other being Fossil armor. This set provides the highest offensive bonuses for the class prior to Hardmode. On, it is the only ranged armor set available in pre-Hardmode.

If the full set is worn, the player leaves an afterimage while running (just like full Shadow armor). In addition, the sound the player makes when taking certain types of damage will be the same as for a Skeleton.

Tips

 * The set bonus stacks with other ammo conservation bonuses. When used with the Megashark, it produces a 60% chance to not consume ammo. Furthermore, using the Ammo Box from the Traveling Merchant will result in a 68% chance not to consume ammo. If an Ammo Reservation Potion is then used, the player's chance not to consume ammo amounts to 74.4%, meaning only approximately every fourth shot consumes a bullet.
 * Given both Cobwebs and Bones in surplus, making Necro Helmets is the most profitable way of monetizing either of them.

Trivia

 * The term  comes from the Ancient Greek word νεκρός (nekrós, "dead").
 * It is the only armor set in the game of a rarity.
