In 1.3.4, an experimental feature setting was added to allow players to see, copy, and input the world seed. Worlds generated in 1.3.4 or later will always have a world seed. The World Seed feature enables the display of the random seed used to generate a Terraria world, and allows the player to input a custom seed manually when creating a new world. For seeds that can be planted, see Seeds. For the ammunition fired from a Blowpipe, see Seed.
