Turtle Shell

The Turtle Shell is a Hardmode crafting material that has a chance of being dropped by the 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, but, since Beetle Armor has two chest variants, you would need 4 Turtle Shells to craft the armor with both chest pieces. On average, you will need to kill about 90 Giant Tortoises for a 90% chance to get 3 Turtle Shells (about 140 for 99%). If you want to get 4 Turtle Shells instead, this number is raised to 110 for 90% chance (and 170 for 99%).

Trivia

 * Despite being called a Turtle Shell, it is dropped by the Giant Tortoise. The only turtles in the game are the Sea Turtle, 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.
