Pandora's Box
Pandora's Box is an arcade-style item mod: one craftable box that, when opened, triggers a random or chosen effect on the player.
What it does
The mod adds a single item, Pandora's Box. It can be crafted, found in dungeons, or added with a cheat command. Opening it activates a random effect on the player, or a specific one when a command names it. Effects include transforming the land around the player into End terrain, giving the player enchanted and sometimes named items, and sending a snake made of blocks through the air while hiding the box itself.
Command blocks can use the box as well. A selector such as player=@p invokes it on the nearest player, and the effect list is shown by typing the effect command and pressing tab for auto completion. Pandora's Box also spawns in special structures, but only when Recurrent Complex is installed; structures are not present in the 1.16.5 build because they would need a full rework without that mod.
The mod runs on Fabric, Forge, NeoForge and Quilt. Both the server and every player need it, because the effects act on the world. Atlas Core, Cloth Config API, Fabric API and Forgified Fabric API are required, and Mod Menu is optional. The code is released under the MIT License and is open source, and the source code and issue tracker are public.
