Developer items

Developer-reserved items are vanity items and Wings that are reserved for particular members of Terraria's development staff. They are unobtainable for ordinary players without the use of inventory editors or other hacks.

In contrast to other unobtainable items, hacking a developer-reserved item into a player's inventory for use is discouraged by inflicting several penalties on any player who equips one. These penalties generally have the combined effect of quickly killing most players. They include the debuffs Blackout, Burning, Cursed, Confused, Slow, and Weak, as well as reducing the player's armor to -1000, reducing movement speed to 1%, and causing intermittent ticks of 5 damage.

Tips

 * 4 of the 6 debuffs can be bypassed by equipping an Ankh Charm or Ankh Shield, leaving Blackout and Burning.
 * Debuffs are not applied if a piece is in an armor slot and a social item covers it. However, this defeats the purpose of wearing it in the first place.

Trivia

 * Crowno's armor resembles a plague doctor costume, a garment worn in 17th century Europe to protect doctors from bubonic plague.
 * Will's armor resembles a minotaur.
 * Aaron's armor resembles Daft Punk's member, Guy Manuel de-Homem Christo.
