Bossmode
by lanse
Bossmode turns mob encounters into boss fights, with a difficulty setting above Hardcore that makes ordinary mobs, passive ones included, much tougher to beat.
What it does
Bossmode adds a difficulty level above Hardcore. Under it, single mobs become bosses, and the setting reaches passive animals as well. Boss fights draw on custom attacks, custom weapons, custom armor and unique mob behavior. Several bosses are very strong, so a player needs to use the resources around them to survive. Commands control the general Bossmode settings and the spawning of bosses. The code is open source under the MIT License, and the mod runs on the server alone, so players join without installing anything. Files cover 1.20.1 – 1.20.6 for Fabric.
