Dreadbolt (after floor 19)

Dreadbolt is the first boss of the Arena floor climb. You reach it after clearing floor 19, and the fight opens with a short cutscene where it taunts you: “HAHAHA! Do you think you can beat me!?” The arena turns yellow and cracked, so it is easy to recognise.

Like every floor fight, it plays out automatically with your three equipped robots. If it beats you, treat it like any other wall: don’t retreat (that sends you back to floor 0), go level up and come back.

Junkyard Titan (event boss)

The Junkyard Titan appears in the Junkyard as an event, with its own health bar across the top of the screen. It is not part of the floor climb. We haven’t confirmed how often it spawns or what it drops yet and will add both here.
