The secret dungeon is a raid consisting of 36 rooms. The goal is to find the spiral portal room, defeat the monster ????? and defeat the two bosses in the final room, Chaos and CHAOS, before the 30 minute timer runs out.

Raid Format

This raid consists of 36 rooms, arranged in a 6-by-6 square. You enter in the bottom right corner, which will always be an empty room. The other 35 rooms include 20 rooms with normal monsters, 4 rooms with boss monsters (rare bosses !!!!! and shinki, the bridge dweller count as normal enemies), 10 treasure chest rooms that may overlap with a normal or boss room, and one room with a red spiral portal in it. Chests can be opened by clicking on them or using the shift key. All enemies in a room must be defeated before you can move. Once you find the portal room, you can click on the portal or press shift to go to the final chamber, where you fight Chaos and then CHAOS. The power of CHAOS depends on the number of chests you opened. Completion of the raid yields a number of rewards.

Entry Limit

You may repeat the raid as many times as you would like. After the 10th entry in a given day, however, enemies give 85% less experience, coins, and pixels. Chaos and CHAOS give 80% less.

Treasure Chests

Each treasure chest that you open gives rewards and increases your final score (see below), but increases the strength of CHAOS.

  • Chest 1 will reveal in white the rooms that have some enemies left. NOTE: The portal room will remain dark grey. Rooms with unopened treasure chests will start flashing between yellow color and normal color with yellow top left corner.
  • Chest 2 will reveal in red the rooms with normal enemies, in the purple rooms with bosses.
  • Chest 3 will reveal in dark red the portal room.

For each chest opened, CHAOS gains:

  • 60% HP
  • 20% Attack
  • 20% Defense
  • 10% Accuracy
  • 10% Evasion
  • 15% Damage from his ranged attack
  • 90% more HP when Healing itself
  • 30% EXP Reward
  • 30% Coin Reward
  • 30% Pixel Reward
  • 1 second of duration for status effects given

(Note: These stack additively, not multiplicatively.)

Additional effects of chests:

  • If 4 or more chests are opened, CHAOS may use the Blue Aura, which reduces damage from all attacks to 1 while it is active.
  • If 6 or more chests are opened, CHAOS may use the Green Aura, which causes attacks to heal him while it is active.  Damage will be dealt as normal, but he will then recover 3x the damage he just took.
  • If 8 or more chests are opened, CHAOS may use the Red Aura, which causes his attacks to deal 2x damage while it is active. All of his attacks do a minimum of 666,666 damage (reduced only by Rest) under this aura.
  • If 10 chests are opened, CHAOS may use the Black Aura, which causes him to harm you by 30% percent of your current HP whenever you damage him while it is active.  This cannot kill you but may reduce your HP to 1.

Other Rewards

If you are in Worst Moon mode, CHAOS armor may drop from CHAOS.  The chance of this happening is (10 + 5 * Chests Opened)%.  This chance increases by 25% in hardcore mode and by 15% in apocalypse mode.  The unobtainium enhancement of this armor is 7 + chestsOpened, with an additional 8 in hardcore and 5 in apocalypse mode.  Therefore, 10 chest hardcore apocalypse mode has a 100% chance of dropping unobtainium enhancement 30 CHAOS armor.

Successfully beating 10 chest hardcore apocalypse CHAOS also gives you the Elixir of Greatness, a 60 minute potion that does nothing.  Its description is "A special potion that once belonged to (yourName), the greatest warrior of Anti-Idle planet. It contains all you need to become as powerful as (yourName)!"

Player also receives (150 + 15 * ChestsOpened) Proof of Training.

Anti-Curse Potion

It used to be possible to buy a potion called the Anti-Curse potion. Having this potion activated when you enter Secret Dungeon removes your chances of obtaining CHAOS armor, substantially lessens your score, and substantially cuts the rare and epic rate of the area while causing enemies to take more damage and deal less damage. The only way to use such a potion, however, is to have one saved from a version when it was possible to buy them.
