Recommended Heroes & Teams
Poison and Paralysis Counters
| Characters with Paralysis Immunity | ||
| Characters with Poison Immunity | ||
Iron Devourer inflicts Poison and Paralysis. To counter this, bring Heroes that can grant immunity to both. Note that Iron Devourer has three heads, but only the center head can receive damage.
Target the Middle Head
Use Focus Target
| Characters with Focus Target | ||
The Iron Devourer has three heads. Attacks to the left and right heads deal only 1 damage, while the center head has reduced HP. The standard strategy is to boost 'Weakness Hit Chance' and use 'Focus Target' on the center head.
| Tips! | If your 'Weakness Hit Chance' is too low and 'Focus Target' ends up on the left or right heads, use the stop button in the upper-right corner to retry. Keys are not consumed when retrying. |
|---|
Weakness Hit Chance Boost Also Works
If your attacker's gear includes Weakness Hit Chance Boost, you can also use a hero with a Weakness Hit Chance Boost skill instead of Focus Target. Biscuit is particularly recommended, as she can simultaneously increase the damage dealt to the boss.
Use Magic Single-Target DPS
Iron Devourer's center head has Physical Resistance and high DEF, so assign Pascal or Yuri as your DPS. Their magic damage bypasses DEF and can deal significant damage.
| Tips! | Wide-area skills generally deal lower damage, so single-target attacks are recommended when facing a single target. |

Recommended Party Example
Paralysis Immunity/Poison Immunity/Single Magic Attacker are essential, and you should also make sure to include a hero with either Focus Target or Weakness Hit Chance Boost. It is recommended to use healers in the remaining slots to increase your survivability,

Iron Devourer Raid Strategy & Tips
Decide Strategy (Focus or Weakness)
When forming party, decide to choose 'Focus Target' or 'Weakness Hit Chance Boost' to go with. Your pick will change depending on the strategy you choose. When DPS is not enough, you may need to combine the strategy to maximize damage to the boss.
Prioritize Healing When HP is Low
When party HP is low, prioritize healing. If sustain is lacking, consider adding additional Healers.
Chip Away HP with Your Attacker
Once the field is set, use your Back Row attacker to chip away at the enemy's HP. Their damage output greatly impacts stage clear, so prioritize their development as much as possible.
Enhance via Power-Up & Rank-Up
To clear high-difficulty Raids, enhancing heroes through Power Up and Rank Up is recommended. If a stage is too difficult, try enhancing heroes to +5 or ranking them up to strengthen your party.
What are Raids?
Obtain Equipment and Crafting Materials
Raids are PvE content where you can earn equipment and crafting materials. Each dungeon has difficulties from 1 to 15 and the higher the difficulty, the better the chance of obtaining high-rank equipment..
| Tips! | Raids unlock after clearing Adventure 4-10. |
