Boss battles are battles that spawn bosses. They differ heavily from Arena Battles. Once apocalypse+ is unlocked, all levels with boss fights are marked as boss missions ().
Spawning[]
Boss battles spawn in certain areas in certain levels. These levels include the Soggy Swamp, Desert Temple, Fiery Forge, Obsidian Pinnacle, ??? (Secret), Overgrown Temple, Lone Fortress, Gale Sanctum, Abyssal Monument, and the Broken Citadel.
Behavior[]
Boss battles are different from arena battles. They spawn one mob: the boss. Bosses are much stronger than common mobs. They are capable of taking hundreds of damage, and can deal significant of damage with a single hit. They can also summon minions (usually common mobs) to help them out with their battle against the hero (one exception is the Heart of Ender). The minions depend on what boss the hero is facing. The Corrupted Cauldron summons pink slimes, the Nameless One summons skeleton vanguards, the Redstone Monstrosity spawns redstone cubes, the Arch-Illager summons vindicators, pillagers, and redstone golems, the Mooshroom Monstrosity summons mooshrooms, the Jungle Abomination summons whisperers and leapleaves, the Wretched Wraith summons strays and wraiths, the Tempest Golem activates squall golems, the Ancient Guardian summons guardians, and elder guardians, and the Vengeful Heart of Ender summons Endermites. No matter what, boss fights are always announced by the game. When bosses are defeated, their loot drops directly from them.
