Bonus Stages are accessed through Special Random Boxes, that will spawn a Portal leading you into the Dimension. You're tasked with collecting Orbs and will be rewarded with Coins and Soul Goblins after each segment.

There's a Special Bonus Stage, which can only appear once you've completed the normal Bonus Stage once. It will stop appearing as soon as you complete it once to unlock the Character Minita. The chance to find this special Portal in a Special Random Box is 7%.

  • You get 30 seconds per segment.
  • If you fall into a pit you get a 2 second time penalty.
  • There's a 2 second lockout between penalties, so that if the game drops you right above the next pit after falling you don't get double punished.
  • Event timers will be paused during the Bonus Stage, but they are still active.
  • Craftable Temporary Items (e.g. Whetstone) will be both paused and inactive. However, the Astral Ascension Upgrade Magical Temporary Item changes this.
  • If you don't manage to collect the required amount of orbs within the time limit, the feature Second Wind will offer you another attempt at the section lost on, if you watch an ad. Note that this will happen only once per Bonus Stage.
  • Random Boxes that spawn in Bonus Stages cannot trigger the Random Events Horde, Frenzy, or Fury.

If you have completed 50 Bonus Stages or more, there is a chance of triggering the Spirit Boost mod for the Bonus Stage. The Spirit Boost mod has a 15% base chance to activate, and that chance can be increased with upgrades. The Spirit Boost mod gives you a short boost to your speed and changes your strategy to completing the Bonus Stage significantly.
