The Dimensional Item Gate Mod (1.21.8, 1.20.1) introduces a powerful mechanic for custom modpacks and progression-based worlds, allowing access to Minecraft dimensions to be controlled by player inventory. Developed with modpack creators in mind, this mod enables you to define precise rules players can only enter a dimension if they carry certain items, or are blocked if they have restricted ones.
