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.
What is a Power Up Dungeon?
Obtain Training Materials
Power Up Dungeons are PvE content where you can get Particles, which are Rank Up Materials, and Gold needed for training. Each dungeon has 10 difficulty levels, and the higher the difficulty, the higher the quantity and quality of the materials you get.
