UAVwaffle's Mob Crystals
by UAVwaffle
UAVwaffle's Mob Crystals lets players seal a mob inside a crystal, so it can be carried in the inventory and released later.
What it does
Shift-right-clicking a mob with a crystal stores it, and the crystal can be used to place the mob back into the world. Stored mobs are kept in a state where time does not pass for them, so they do not become lonely while sealed. The mod works with villagers, which can also be sealed with a shift-right-click.
The mod is configurable: a whitelist and a blacklist decide which mobs can be sealed, and config options set the maximum mob health, which defaults to 50, and the maximum stack size, which defaults to 16. Some mobs cannot be sealed because of the way Minecraft processes right-clicks, and dogs and horses are among them. The author notes that demand could lead to a fix for this.
The mod is published for Forge only, for 1.20.1, with the file 1.20.1-1.0.0-FORGE from 2025-03-17. The server and every player need the mod installed. The code is under the GNU General Public License v3.0 only and is open source, with public links to the source and the issue tracker.
