Turtle Shell

The Turtle Shell is a Hardmode crafting material that has a 1/17 (5.88%) chance of being dropped by Giant Tortoises in the Hardmode Jungle and Underground Jungle.

Turtle Shells are used solely to craft Turtle armor, which can in turn be used to craft Beetle armor. Crafting all pieces of Turtle armor requires a total of 3 Turtle Shells. On average, you will need to kill about 90 Giant Tortoises for 90% chance to get 3 Turtle Shells (about 140 for 99%).

Trivia

 * Despite being called a Turtle Shell, it is dropped by the Giant Tortoise. The only turtles in the game are the Pet Turtle,Turtle Mount, Turtle, and the Jungle Turtle.
 * Even though it has a higher drop rate than the Bezoar, it is rarer overall due to the Giant Tortoise's relatively low spawn rate.
