Thief's Trinket is a trinket. It can only be found in the Curio Display of a Grand Heist, from Smuggler's Den or Underbelly, as they have the "Thief's Trinket" heist target type.
In order to equip it, players need to run a Smuggler's Den or Underbelly Grand Heists, and click on The Catch sculpture next to the Curio Displays.
The 5 to 1 vendor recipe yields a random corrupted Thief's Trinket. The vendor offer is shown as a hidden item in the Sell screen, so that it is not possible to see which modifiers the resulting Thief's Trinket will have before committing to the sale.
