开发者物品 are 时装物品 and 翅膀 that were made for particular members of Terraria's development staff.
A random set of developer items can rarely (1/20 or 5% chance) drop from a 困难模式 Boss's 宝藏袋 in an 专家模式 world.
- All Developer's Wings have a flight time of 2.5 seconds.
- Some of the coloration on Arkhalis's clothes depends on the colour of the player's clothing.
- On the
主机版 and 
移动版, developer items are 无法获取 legitimately, and can only be obtained via glitches or exploits. On the mobile version, any developer items in the player's possession will vanish upon exiting the world.
- Developer items, along with the 可疑触手 and 0x33飞行员, are the only 专家模式-exclusive items that don't have the rainbow 稀有度.
- Some items (unlisted) were used by the developers during game testing, and were removed from normal gameplay, making them 无法获取: 红药水 and Zapinator枪 (the Zapinator was later released on 3DS).
- These were 无法获取 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.
- 1.3.5: Added Arkhalis's clothes and Leinfors's clothes.
- 1.3.0.4: Red的抛球 and 女武神悠悠球 added to their respective sets.
- 1.3.0.2: Removed non-developer killing effect when worn in all modes.
- 1.3.0.1:
- Removed non-developer killing effect when worn in Expert Mode.
- Now obtainable from Treasure Bags as a rare drop.
- Added Loki's, Yoraiz0r's, Lazure's and Skiph's armor sets.
- Red's wing no longer have infinite flight.
- Changed tooltip from "You shouldn't have this" to "Great for impersonating devs!"
- 1.2.0.2: Added non-developer killing effect.
- 1.2: Introduced, but unobtainable.
