This is a lineup that consists of low-rarity, and F2P options. Heavenia functions as the main DPS, but she can also be substituted with Lania if you don't have her.
Burn Immunity is a Must
The enemy inflicts Burn and deals additional damage to targets with Burn, so having a countermeasure for Burn is essential. Be sure to include a Hero with Burn Immunity in your party. Note that the aforementioned Jave and Juri only apply this to themselves.
Inflicting Freeze is Effective
In the Fire Particle Dungeon, the status ailment "Freeze" is very effective. Actively include Heroes that can inflict Freeze as your status ailment attackers.
Tips for Clearing the Fire Particle Dungeon
Attack with Heroes that Inflict Freeze

Basically, it's recommended to keep attacking with the Freeze-inflicting skills of your Heroes that can inflict Freeze. The enemy goes berserk after 30 turns, and its attack power increases every 10 turns after that, so the longer the battle, the more disadvantageous it becomes.
Prioritize Healing and Barriers at Low HP

If your party members' HP gets low, prioritize recovery with Healing or creating Barriers over inflicting Freeze. If you can't heal in time, it's also a good idea to try adding more Tanks or Healer Heroes.
Strengthen Heroes as Needed

To clear high-difficulty Raids, 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.
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 Rank of the Materials you get, and the more you get.
