Basic Information

Secret Dungeons are dungeons that can be accessed at Lv.99 and stages are separated by Combat Power. There are no item drops in this game mode and rewards are fixed depending on the difficulty tier you completed. EXP and ED rewards can only be increased using exclusive title and accessory from secret dungeons. Barrier Fragments, which are obtained upon clearing Secret Dungeons (with the exception stage 4 and above Secret Dungeons), can be exchanged at an Elysion Tree for ED and El Rewards.

How to Enter

To unlock and enter Secret Dungeons, the character must fulfill the following requirements:

  • Achieve Level 99
  • Each account is given 5 weekly reward. Rewards are shared among characters.
    • After rewards are received, you will still be able to enter the dungeons. However you will not be able to receive any EXP, ED or drops.
    • Additional runs can be done to complete Prof. Pho 3rd growth guide lesson 5.
