The banner that pops up right before a battle between a Boss starts.

"Boss inside. You have been warned."

Bosses are strong enemies with high damage and hp found on the 5th level of each floor (levels x-5). Based on the current terrain, Bosses are chosen at random.

After defeating a Boss in level mode, a Golden Chest with higher chance of dropping a rare, epic, or legendary weapon will spawn. This does not occur at 3-5, as there is no point in giving the player a weapon after the game is over. However if the player has Loop Mode on, a golden chest will spawn.

Sometimes the summoned minions of the Boss will still be alive even after its death. This can happen if the boss dies before the minions appear from the summoning attack, as any minions already summoned will die with the boss.

Since version 1.5.1, Boss rooms are indicated by red entrances in some versions, which turn normal after entering the room. This entrance is not to be mistaken with an all-champions room, in which all the enemies in the room are Champions. Two Bosses will spawn if the player has the “Fight with 2 slightly nerfed bosses in each Boss room” Challenge condition.

  • This condition can spawn bosses from different biomes. It will also cause static bosses to be offset from the center, as there are now two bosses. The Boss arena is always the one of the left Boss, which spawned first.
    • This can be confusing, as the player will see a boss from a different biome as the right boss from time to time.

Enraged Phase

If the Boss has less than half of total HP, it will become enraged Baka!.png and will start to use more powerful attacks, as well as attacking much faster and more aggressively. In addition, Enraged Bosses will recover from debuffs much faster than usual (1 second instead of 2). At half of its total HP and upon death, they will also drop 10 energy orbs for players to recover. Upon death, they will drop a lot of Gold, materials and energy.

There are exceptions, however:

  • The Giant Crystal Crab and the Giant Golden Crab can restore health during the enraged phase, but restoring over half HP once enraged does not stop the enraged phase. This goes with Cave Ice Bug when it eats a ice crystal. Anubis can also indirectly heal by summoning Staff Mummies.
  • The Baby Dragon Bros have separate health bars, but they're shown as one. This means that either one will become enraged once their health drops below half.

Trivia

  • Before version 1.3.5, Bosses used skull symbols Yummy~.png when enraged.
    • The symbol used now is pulsing veins.
  • Special music will play during the fight.
  • Goblin Priest is the only 1-5 boss that can drop any of the 6 magic fragments.
  • Before Update 1.4.1, there used to be two portals that appeared after beating the first boss. The left one took the player to the Knight floor and the right one took the player to the Dungeon floor.
  • A glitch occurred in version 2.3.0 such that boss shockwaves were much bigger than expected.
