Bosses' Addition

Description:

Are you bored of fighting the same old vanilla mobs? Bosses' Addition introduces 5 unique bosses, each one more powerful than the last! Face off against these customized vanilla mobs with increased stats and special gear. All of this is done entirely in vanilla Minecraft, no mods required!

How It Works:

  • Use /trigger easyboss to summon the easiest boss, balanced for iron-tier players.
  • Progress through harder bosses using /trigger mediumboss, /trigger hardboss, and /trigger extremeboss.
  • Challenge the Final Boss with /trigger finalboss—a massive, heavily-armored undead with a Soul Reaper Bow and 500 HP!
  • Each boss spawns above you and comes fully equipped with gear, weapons, and buffs.
