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 exclusivity. They are only accessible via inventory editors or other third-party game modifications.

Unimplemented items are items that are partially present in the game files, however, due to their incomplete coding, they cannot be obtained, even with inventory editors.

These items are all either illegitimately obtained or were already in a player’s inventory as a sort of legacy item on the above platforms.

Unobtainable Trapped Chests
The following Trapped Chests were given new ids when it was reported that they were glitched. The new ids are 3886 (Trapped Crystal Chest), and 3887 (Trapped Golden Chest)

The glitched chests still exist in the game code, but cannot be crafted or otherwise obtained. When edited into the inventory, they take the appearance of a Golden Chest and a Crystal Chest in-game. Mousing over them will freeze the player's character.

Unobtainable walls
Many of the natural walls are now obtainable in the Graveyard Biome with the use of Ecto Mis t and a workbench.

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 Zapinator is actually obtainable on the as a drop from Plantera.
 * The sprite for a Water Fountain that is not currently in the game can be found in the game files.
 * The only unobtainable Luminite tool set with a name in the game codes is the Stardust set, while the others are just named Unknown.
 * The Icemourne and the Scythe are obtainable on the through the use of inventory management software. The Icemourne will have the description of the Boreal Work Bench, and the Scythe will have the description of the Boreal Wood Table, but the sprites will remain as their respective original sprites. Both have their swing animations but no damaging hit boxes, and may also place as Angel Statues.
 * All Developer items edited in on the will have the tooltip "You shouldn't have this" and will disappear upon selection (no button to wear the vanity set, no matter how much of the item, will always say "0 items in inventory"), except for the Red's Wings, that can make the player fly indefinitely.
