Boss Buff is a mod that lets you fully configure the core combat attributes of every boss in Minecraft. Whether you're fighting the Wither, the Ender Dragon, or any boss added by a third-party mod, Boss Buff gives you direct control over how tough, fast, hard-hitting, and resilient each one is.

The mod targets five key attributes that define how a boss feels in combat:

Max Health — set how many hearts a boss has, from a minor increase to a massive health pool that turns every fight into an endurance battle.
Movement Speed — make bosses slower for a more tactical fight, or push their speed to the limit for a terrifying chase.
Damage — raise or lower how hard a boss hits, making encounters as punishing or as forgiving as you need.
Armor — increase physical protection so bosses can shrug off most attacks, forcing players to use stronger gear or smarter strategies.
Armor Toughness — reduce the effectiveness of high-damage hits, making armor more consistent and the boss harder to burst down.

All five attributes are independently configurable per boss through a simple config file generated on first launch. You can apply global multipliers for a quick difficulty boost, or fine-tune each boss individually for a fully custom experience.
