Iron Devourer Raid Tips and Strategies

Paralysis and Poison Countermeasures are a Must

Paralysis Immunity Characters
Victoria	Xiao Qiao

Poison Immunity Characters
Lucy

The enemy inflicts Paralysis and Deadly Poison. Without countermeasures you'll be at a serious disadvantage, so be sure to include heroes with Paralysis Immunity and Poison Immunity in your team.

Targeting the Back Row is Extremely Important

Examples of Weakness Hit Chance Boost Heroes
Rachel	Catty	Biscuit

The Iron Devourer has three heads, and all damage dealt to the left and right heads (Front) is reduced to 1. The center head (Back) appears with reduced HP, so target it with Weakness Hits or Focus Target.

Tips!	Weakness Hit Chance can be increased by 15% with a 2-piece Bounty Tracker equipment set, or 35% with a 4-piece set. It can also be granted through equipment options.

What is a Weakness Hit?

1. Use Asura's Focus Target

Focus Target Characters
Asura

Asura has a high Weakness Hit Chance, and can apply Focus Target with Skill 1. By slightly boosting Asura's Weakness Hit Chance with Bounty Tracker equipment or a Rachel build, the standard strategy is to apply Focus Target to the center head.

Tips!	At Rank 6, Asura's Passive alone gives a 70% Weakness Hit Chance, but if Focus Target ends up on the left or right head instead, use the pause button at the top right of the screen to retry.

Advanced Players Can Also Build Without Asura

With a skill-enhanced Biscuit, her skill can grant your Attacker a 54% Weakness Hit Chance. If your Attacker also equips gear with a Weakness Hit Chance Boost option, clearing without Focus Target is also possible.

2. Remove Defense Reduction with Debuff Removal

Examples of Debuff Removal Heroes
Lucy	Orly	Miho	Xiao Qiao
Guan Yu	Lee Joohee	Yoongun

When the enemy uses its Defense Reduction skill, remove it early with Debuff Removal. You can clear lower difficulties without it, but the higher the difficulty, the harder it becomes to clear without Debuff Removal.

3. Attack While Using Buffs and Debuffs

Best Attackers
Pascal	Yuri	Xiao Qiao

Attack with your Attacker while using buffs and debuffs. The Iron Devourer has high Defense and also has a Physical Resistance passive skill, so the best choice is a single-target Magic Attacker capable of Ignore Defense attacks.

Tips!	Skills tend to deal less damage the wider their attack range, so single-target attacks are best in battles against a single enemy.

4. Set Up the Field Before the Cooldown Resets

Examples of HP Healing Heroes
Karon	Yui	Lina	Lucy
Orly	Sun Wukong	Lee Joohee	Heavenia

After attacking, it's best to use the downtime before you can attack again to heal HP and set up Buffs/Debuffs. From there, just repeat the steps from step 1 onward according to your Buff/Debuff situation.

Progress Your Hero Upgrades Through Enhancement and Evolution

To clear higher-difficulty Power Up Dungeons, upgrading your heroes through Enhancement and Evolution is essential. If you can't clear a stage, try Enhancing your team members to +5 or Evolving them.

Biscuit

Lucy

Pascal

Xiao

Xiao Qiao

Buff/Debuff

Poison Immunity

Main DPS

Buff/Debuff
Barrier
Heal

Paralysis Immunity

This team uses Lucy for Poison Immunity, Xiao Qiao for Paralysis Immunity, Biscuit and Xiao for Buffs/Debuffs, and Pascal to whittle down HP. Make sure to boost Xiao and Pascal's Weakness Hit Chance with equipment.

	Around 90%	The higher, the more stable your clears
	As high as possible
	Up to 10%	Reaches 100% with Passive + Biscuit's buff

	As high as possible	Highest or 2nd highest in the team
	0%	At T6, Skill 2 Crit Rate is 100%
	As high as possible
	Around 40%	Around 90% with Biscuit's buff
	31+	Blocks attacks while under Defense Reduction

Since you need to target the back head, it's ideal for Xiao/Xiao Qiao/Pascal's Weakness Hit Chance to be close to 100% including buffs.

By keeping 4 or more heroes' Speed higher than the enemy's 30, you can prevent taking damage in the window between Defense Reduction landing and it being removed.

Best Equipment & Rings

Hero	Equipment	Ring (Refining)
Biscuit
Lucy
Xiao
Xiao Qiao
Pascal

For support heroes, the Ring of Resurrection is best, and for Attackers, the Ring of Subjugation (Boss Ring) is best. However, if your Attacker tends to get taken out mid-fight, equipping the Ring of Authority is also an option.

Best Pets

Ideal	Alternative	Alternative	Low Rarity
Windy	Yeonji	Igris	Note

Windy, who can inflict Boss Vulnerability, is the Best pet choice. If you don't have her, substitute with Yeonji or the collab rare pet Igris.

Alternative Heroes

Best Pick	Alternative Heroes	Notes
	Asura	Focus Target
	Lina	Alternative for Buff/Debuff
	Sun Wukong	Doubles as Attacker and Healer
	Victoria	Alternative for Paralysis Immunity

Note that if you use Lina instead of Xiao, Defense Reduction won't be applied to the back row unless she's at 6th Transcendence. If your Sun Wukong is well-developed, adding him for an extra Attacker is also a viable option.

Auto-Skill Priority

Priority	Skill	Hero
1	Skill 1	Biscuit
2	Skill 1	Xiao Qiao
3	Skill 1	Xiao
4	Skill 2	Xiao Qiao
5	Skill 2	Pascal
6	Skill 1	Pascal

Setting Xiao Qiao's Skill 1 as priority 2 lets you remove Defense Reduction with Debuff Removal right away. If any of your heroes tend to get taken out mid-fight, consider equipping a Legendary ring to counter it, or inserting Lucy's healing skill in between.

Intermediate Teams

Team Formation: Defense

Asura

Lucy

Pascal

Lina

Xiao Qiao

Focus Target

Poison Immunity

Main DPS

Buff/Debuff
Heal

Paralysis Immunity
Buff/Debuff
Barrier

This team uses Lucy for Poison Immunity, Xiao Qiao for Paralysis Immunity, and Asura to apply Focus Target so Pascal can whittle down the boss's HP. With Focus Target active, everyone except Asura no longer needs to boost their Weakness Hit Chance through equipment.

Target Stats

Hero	Target Stats	Notes
	50%+
	32%+
	20% or less	100% via Passive
	31+	Blocks attacks while Defense Reduction is active

	As high as possible

	As high as possible
	0%	T6 gives 100% Crit Rate on Skill 2
	As high as possible
	31+	Blocks attacks while Defense Reduction is active

Make sure Asura's Weakness Hit Chance reaches 100% when combined with her Passive, so she can apply Focus Target to the back row.

By keeping at least 4 heroes' Speed higher than the enemy's 30, you can prevent the party from taking damage between when Defense Reduction lands and when it's removed.

Best Equipment & Rings

Hero	Equipment	Ring (Refine)
Asura
Lucy
Lina
Xiao Qiao
Pascal

Lina's best pick is an HP Ring to boost her healing output. DPS heroes are best paired with a Boss Damage Ring, but if they tend to get knocked out mid-fight, equipping the Ring of Authority is also a solid option.

Best Pets

Ideal	Alternative	Alternative	Low Rarity
Windy	Yeonji	Igris	Note

For pets, Windy is the best choice since she can inflict Boss Vulnerability. If you don't have her, Yeonji or the collab rare pet Igris are good substitutes.

Alternative Heroes

Best Pick	Alternative Heroes	Notes
	Biscuit	Weakness Hit Chance Boost
	Xiao	Alternative for Buff/Debuff
	Sun Wukong	DPS and Healer in One
	Victoria	Alternative for Paralysis Immunity

If Biscuit is well-developed, she's better suited for fast clears. If Sun Wukong is built up, running him to add another DPS is also a solid option.

Auto Skill Priority

Priority	Skill	Hero
1	Skill 1	Asura
2	Skill 1	Xiao Qiao
3	Skill 2	Xiao Qiao
4	Skill 2	Pascal
5	Skill 1	Pascal

Setting Xiao Qiao's Skill 1 as the 2nd priority lets you remove Defense Reduction right away. If a hero tends to get knocked out mid-fight, equipping a Legendary Ring is one countermeasure, or you could also slot Lina's healing skill in as the 4th or 5th priority.

Early-Game Party 1

Front	Front	Front	Front	Back
Asura Focus Target Debuff	Lucy Healer Poison Immunity Debuff Removal	Rachel Buff/Debuff	Ace Debuff	Xiao Qiao DPS Paralysis Immunity Debuff Removal Buff/Debuff

In the early game, bringing Asura for her Focus Target and using Rachel to raise Weakness Hit Chance tends to make runs more stable.

Early-Game Party 2

Front	Front	Front	Front	Back
Victoria Paralysis Immunity	Lucy Healer Poison Immunity Debuff Removal	Rachel Debuff	Ace Debuff	Sun Wukong DPS Healer

We recommend challenging the Iron Devourer raid after you obtain Xiao Qiao, but if you can't wait, substitute Victoria for Paralysis Immunity and bring Sun Wukong as your DPS. Since Sun Wukong can hit 3 or more enemies at once, Focus Target isn't needed.

Tips!	While Repeat Battle is running, you can minimize the game and take on Adventure, Arena, Infinite Tower, and more — just like with Ruby farming.

What is a Raid?

Get Equipment and Crafting Materials

A Raid is a PvE content type where you can obtain equipment and equipment crafting materials. Each dungeon has difficulty levels from 1 to 15, and the higher the difficulty, the more likely you are to get higher-rank equipment.

Tips!	Raids become available once you clear Adventure 4-10.
