Turtle Shell

Turtle Shells are a rare drop by Giant Tortoises in the Hardmode Jungle Biome (both surface and Underground). They are used to create Turtle Armor. While a player only needs a grand total of three shells to craft the complete set (four for both beetle chestplates), you may find yourself hanging out in the Jungle for a long time due to the Giant Tortoise's toughness and spawn rarity.
