Minecraft Dungeons:Boss Battle

Boss Fights are battles that spawn bosses. They differ heavily from Arena Battles.

Spawning
Boss Fights spawn in certain areas in certain levels. These levels include: Soggy Swamp, Desert Temple, Fiery Forge, Obsidian Pinnacle, ??? (Secret), Overgrown Temple, Lone Fortress, and Gale Sanctum.

Behavior
Boss Fights are different from Arena Battles. They only spawn one mob: the boss. Bosses are much stronger than common mobs. They are capable of tanking hundreds of damage, and able to deal tons of damage with a single hit. They are also capable of summoning minions (usually common mobs) to help them out with their battle against the player (one exception is the Heart of Ender). The minions depend on what boss the player is facing. The Corrupted Cauldron summons Pink Slimes, the Nameless One spawns Skeleton Vanguards, the Redstone Monstrosity spawns Redstone Cubes, and the Arch-Illager summons Illagers. No matter what, boss fights are always announced by the game. When bosses die, their loot drops directly from their corpse.
