Terraria’s version 1.4 update, named Journey’s End, was released on May 16 to mark the 9th anniversary of the game, and according to Re-Logic, it is the final major feature update to the game. The changelog is pretty long and detailed here, but the summary is that this update brings about the addition of new items, mechanics and features to the game, one of which is Journey Mode.
Journey Mode is a new addition to the options that a player can select during the creation of a new world or character. It starts the player with extra equipment (fledgling wings, magic mirror), and more importantly, gives the player access to the Power menu. In short, Journey Mode gives players a lot of new powers and settings which can be enjoyed only when it is selected. One of these powers is the ability of players to duplicate items. In this guide, we’ll see how to duplicate items in Terraria 1.4, but not only that; I’ll also show you how to duplicate any item that requires just one chest using a glitch introduced in this new update!
