Developer items

Developer items are vanity items and Wings that were made for particular members of Terraria's development staff.

On the, a random set of developer items can rarely (1/20 or 5% chance) drop from a Hardmode boss's Treasure Bag in an Expert Mode world. These were unobtainable before the 1.3.0.1 update, and if somehow worn they would inflict a variety of debuffs on the wearer, thus rendering them useless.

On the and, developer items are unobtainable legitimately. If received through glitches, hacks, or inventory editors, the items, unlike the Desktop version before the 1.3.0.1 update, will not give any debuffs to the player.

Trivia

 * Jim's Wings act similar to the Hoverboard in the fact that when not in use, they do not appear on the characters back.
 * In Terraria's source code, the 'name' stats for Yoraiz0r's items read as follows (the 'name' stat is mostly deprecated in favor of a separate language file, and is now used mainly for source code readability):
 * Uniform: "If you're reading this, hi"
 * Skirt: "Yes, this is my dev armor, deal with it."
 * Spell: "Isn't this glorious?"
 * Scowl: "Dark..."
 * Goggles: "Tetsokun"
 * Before 1.3.0.1 Red's Wings had a infinite flight time.
 * Along with the Suspicious Looking Tentacle, developer items are the only expert mode exclusive items that don't have the rainbow rarity.
 * Before 1.3.0.1, if hacked or obtained into a players inventory, the Developer items would say "You shouldn't have this".
