It's essential to include Feng Yan or Lania for Freeze Immunity and Chloe to prevent the boss from healer, and the remaining heroes can be adjusted according to your roster.

The enemy inflicts Freeze with its Skills and is guaranteed to apply its effect, so having a countermeasure for Freeze is essential. Be sure to include heroes with Freeze Immunity in your party.

In the Water Particle Dungeon, the status ailment "Poison" is very effective. You should proactively include heroes who can inflict Poison as status ailment attackers in the early game.
Tips for Clearing the Water Particle Dungeon
Attack with Poison-Inflicting Heroes

The basic strategy is to apply Poison with the skills of your Poison-inflicting heroes. The enemy becomes enraged after 30 turns, and its damage increases every 10 turns after that, so the longer the battle goes on, the more of a disadvantage you'll be at.
Prevent the Boss from Healing

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?
