Historically, "dupe" scripts attempt to exploit game vulnerabilities to clone items like Lucky Arrows , Corpse Parts , or Event Presents .

Modern YBA scripts often include comprehensive GUIs with features like Item ESP (finding items through walls), Auto-Farm , and Godmode .

YBA developers frequently release updates to patch major duplication glitches. For instance, past holiday themes and specific item spawn rates have been adjusted to combat mass item farming.
