Dungeon Summary

First two waves consist of Robot-type cards. Gears will also appear that can be cardified.

The Boss of the dungeon is Water.pngCronos, who is weak to Wood.png, Paralyze, Confuse, Blind.

On Demon difficulty (72 STP) or higher, Water.pngCronos type-0 has a chance to replace Cronos as the boss.
Defeating Cronos type-0 will grant you additional points. It has the same weaknesses as Cronos.



  • Cronos will charge up every turn, and after a number of turns (3-5 depending on difficulty), will unleash its devastating Destroy Ray attack against the Party. However, if you manage to inflict Paralysis, Confusion, or Blind, Cronos will be forced to dump his charges. (On higher difficulties, it's effectively a wipe if you let Cronos get his Destroy Ray off.)
  • Cronos can also inflict Petrification and has an attack that will deal 2x damage to Petrified targets.
  • He can also inflict Debuffs with his attacks as well as wipe Shields every so often.
  • Debuffs can be quite handy for keeping Cronos' stats down; he buffs himself quite quickly on higher difficulties and hits very hard.
  • If you debuff Cronos too much, he'll clear his Debuffs, so watch out!

Cronos type-0

  • Type-0 is a little similar to regular Cronos, but with some differences.
  • Like Cronos, Type-0 will charge up every turn and after a number of turns (1-2 depending on difficulty), will unleash its Destroy Ray attack against the Party; what's significant here is that he'll Buff himself for a lot for each charge (+2-3 on higher difficulties). Debuff cards are necessary to keep him under control. Inflicting Type-0 with Paralysis, Confusion, or Blind will cause him to hit himself and dump his charges.
  • Type-0's Destroy Ray is a little different in that it has different effects depending on the charge he uses (these are semi-random):
    • The α Charge will result in a α Ray that deals heavy damage and inflicts Damage UP.
    • The β Charge will result in a β Ray that deals heavy damage and wipes all Buffs.
    • If Type-0's Buffs get too high, he'll start using an EX Charge. If you can't force Type-0 to dump his charge, he'll do a powerful 5-hit AoE attack and inflict Status Effects on the Party.
  • Type-0 can also inflict strong Debuffs, Taunt and Petrification with some of its attacks.
  • He can also occasionally apply various Shields (Iron Wall, Status Reflect, or Counter)

Recommended Cards

  • Attackers: Wood-elemental Cards and Cards that can inflict Confusion, Blindness, or Paralysis (Qued, Bivouac, Harushuto, Sagittarius, Jeanne, Asmodeus, Chloe, etc.),
  • Support: Power-Up Enhance, Debuffers (Pisces, Izanami, etc.), Healers/Buffers (Torte, Ceres, Spica, Gemini)
