The Pandoras Box
Pandoras Box puts a block into the world that produces random items at intervals, and it also opens a new dimension reached through a portal.
What it does
The mod installs a block that produces random items at intervals. Players sacrifice items to shorten the countdown, and the block can store up to nine rewards. Hoppers can feed it, so the whole cycle can be automated. Eight pieces collected from the reward chance are crafted into a Pandora Igniter, which activates a gilded blackstone portal leading into the Pandora Realm, a dimension that combines compatible biomes from Minecraft and other installed mods. Client and server both need the mod, and it is published for Fabric only, across 1.21.1 – 1.21.11 with 1.2.33 as the latest file.
Key features
Random reward block

Sacrifice and storage
Sacrificed items reduce the countdown, and up to nine rewards can be stored until they are taken.
Pandora Realm dimension
A new dimension is opened with an igniter and portal, built from compatible biomes of Minecraft and installed mods.
