Realms Reborn is a datapack I made for my Minecraft server that adds a bunch of new recipes, fixes some vanilla recipes, adjusts some structure loot tables, and adds two new structures.
Spawns in mega taiga biomes
The witches gathering spawns in swamps and taigas and the cage can spawn with a few different hostile mobs in it
One vindicator now spawns at the top of all pillager outposts
