Turtle Shell

Turtle Shells are a Hardmode crafting material that have a 1/17 (5.88%) chance of being dropped by Giant Tortoises in the Hardmode Jungle and Underground Jungle.

They are used solely to craft Turtle armor, which crafts Beetle armor. Crafting all pieces of Turtle armor requires a total of 3 Turtle Shells.

Trivia

 * Despite it being a Turtle Shell, it is dropped by the Giant Tortoise. The only turtles in the game are the pet turtle and the turtle mount.
 * Even though it has a much higher chance of being dropped than the Bezoar, it doesn't drop quite as frequently, which is due to the Giant Tortoise's low spawnrate.
