Boss area woof
by RoroBento
Boss area woof lets server owners define fight arenas with a wand and run boss sequences inside them for Fabric 1.20.1.
What it does
A wand marks the two corners of a region, and the area is created from that selection. Each area stores its bounds, a mob wave, an ordered list of bosses and a victory teleport. The data is kept in the world's data/bossarea.dat file, so areas survive server restarts. Commands accept an area name and support tab-autocomplete, and the info page shows the full configuration with clickable buttons that pre-fill commands in the chat bar.
Zombies appear in the middle quarter of an area, between 37.5% and 62.5% on each axis, and only where the floor is solid and valid. The base wave is 10 zombies, with 25% more for each player beyond the first, plus one flat zombie per extra player. The order is changed with reorderboss, and a boss end sequence runs when the fight finishes.
The mod is aimed at adventure modpacks and custom servers that build RPG-style fight areas. Installation needs Fabric 1.20.1, and the commands need operator permission level 2. Installation covers the server and each player's game.
Key features
Selection wand
A wand shows the selected corners as a particle outline, visible while the wand is held and refreshed continuously.
Boss sequence
Bosses spawn in a fixed order, and the next boss waits until the previous one is defeated.
Mob waves
Zombie waves scale by player count, and setmobs replaces the entire mob list with one command.
Datapack functions
Custom NBT and datapack functions can be attached to the area, and a victory teleport moves players after the fight.

Use cases
Who it’s for: Pack makers and server owners who run RPG-style fights need operator permission to set areas up. Players join a server with the mod installed and need nothing extra on their own side beyond the same Fabric 1.20.1 setup.
How it compares
Mob Difficulty RPG is a Fabric client and server mod for 1.20.1 with an all rights reserved license, and it adjusts mob difficulty rather than building arenas. Bossmode is server-side only, open source under the MIT License and published for 1.20.1 – 1.20.6, so players can join without installing anything. Wands & Wizardry is client and server, all rights reserved, and covers 1.20.1 – 1.20.4 with a magic theme rather than arena scripting.
