Instanced Dungeons
by TheRedBrain
Instanced Dungeons adds a Fabric dungeon minigame for 1.21.1 in which each player or team gets a private copy of a dungeon inspired by the Barrows Brothers dungeon from Old School RuneScape.
What it does
Each dungeon structure exists separately from the player's own world, and every player or team that enters receives a private instance to explore on their own schedule. Players can join teammates' instances, so a group can enter the same copy together.
An instance can be reset by its owner, which regenerates the structure with a new random layout for another run. Built-in data packs add dungeon entrance structures to the overworld, and each entrance leads into the matching dungeon instance. When a player leaves an instance, they are returned to the coordinates where they entered.
Script Blocks supplies many of the blocks and features the mod relies on, and Instanced Dungeons also requires Fabric API, Fzzy Config, Lootable Blocks and SmartBrainLib. Client and server both need it, so the server and every player must run the same build. Files are published for Fabric only, for 1.21.1, under the MIT License, and the source code is open source.

Instance reset

What the author says
Instanced Dungeons are dungeon structures which exist separately for each player. This means that each player has their own instance of this structure, allowing all players to explore the dungeon at their own time.
