Pandoras Box adds a mysterious block that periodically generates random items from every installed mod. Sacrifice items to reduce the countdown, store up to nine rewards, and automate everything with hoppers.
Each reward has a chance to generate a Pandora Fragment. Collect eight fragments to craft the Pandora Igniter, activate a gilded blackstone portal, and enter Pandora Realm — a dimension combining compatible biomes from Minecraft and your installed mods.
Reward timing, item filters, exclusions, sacrifices, and automation options can be configured through Mod Menu.
Feel free to use this mod in modpacks.
