Unobtainable features

Unobtainable items are items that are unavailable in the game through regular play. This can occur for various reasons, ranging from copyright liability to exclusiveness. They are only accessible via inventory editors or other third-party game modifications.

Unimplemented items are items that are present in the game files, however they cannot be obtained, even with inventory editors.

Trivia

 * Attempting to give an item with the Biome Key Mold's former ID will result in it switching to a Biome Key
 * The item code for the Icemourne and the Scythe are now Boreal items, the Soul Scythe is now the Red Potion, and the Zapinator is now Bottled Water.
 * The sprite for a Water Fountain that is not currently in the game can be found in the game files.
 * As of 1.3.1, there are several sprites that were never added- one is a set of Hallowed themed Crystal furniture, probably to be crafted with Crystal Blocks. There are a number of gaps in existing furniture sets, which will probably be filled in a future update.
 * Item IDs 3705 and 3706 remain unused.
