Merparrow | Kree | Pike | Nikki | Hellepin |

Death Immunity is Required
| Characters with Death Immunity |
|---|
Leo |
The enemy inflicts Death with its Basic Attacks and Skill 1, so having a countermeasure for Death is essential. Be sure to include heroes with Death Immunity in your party.
Inflicting Bleed is Effective
| Characters with Bleed | ||||
|---|---|---|---|---|
Bi Dam | Leo | Soi | May | Rei |
Bai Jiao | ||||
In the Dark Particle Dungeon, the status ailment "Bleed" is very effective. You should proactively include heroes who can inflict Bleed as status ailment attackers.
Having Debuff Removal is Even Better
| Characters with Bleed | |||
|---|---|---|---|
Ace | Rudy | Spike | Yu Shin |
Orly | Miho | Sarah | Hellenia |
Karin | Lucy | Chloe | Bai Jiao |
When the enemy uses its Defense Reduction skill, it's recommended to remove it quickly with Debuff Removal. You can clear lower difficulties without it, but it becomes more necessary as the difficulty increases.
Tips for Clearing the Dark Particle Dungeon
Attack with Bleed-Inflicting Heroes

The basic strategy is to apply Bleed with the skills of your Bleed-inflicting heroes. The enemy becomes enraged after 30 turns, and its firepower increases every 10 turns after that, so the longer the battle goes on, the more of a disadvantage you'll be at.
Dispel the Defense Reduction
When the enemy uses Skill 2, your defense will be lowered, so it's best if you can dispel the debuff with a Debuff Removal. As the difficulty increases, the importance of Debuff Removal also increases.
Prioritize Healing or Barriers When HP is Low
If your party heroes' HP gets low, prioritize recovering with Heals or Barrier generation over inflicting Bleed. If you can't heal in time, it's also viable to include more Tanks or Healers in your team.
Strengthen Heroes as Needed

To clear high-difficulty Power Up Dungeons, training such as Powering Up and Ranking Up is essential. If you can't clear it, try Powering Up your party members to +5 or Ranking them Up.
Unlock Hero Potential

To clear high-difficulty Power Up Dungeons, increasing Hero Potential is essential. If you are struggling to clear, try increasing the Hero Potential of your party members.
