Tips To Team Up

DPS With Fire or Physical Type Is Recommended

Although the Doomsday Beast's body has no Weaknesses or Resistances, both its hand parts and Antimatter Engine are weak to Fire-type attacks. Once all parts are destroyed, the Doomsday Beast's body must also be reduced to zero HP within one turn. Therefore, it is recommended to use a Physical-type DPS that can exploit the weakness of the durable Engine.

Also Include A Fire-Type Character For Toughness DMG

Each part of the Doomsday Beast is weak to Fire-type attacks and acts every turn. To trigger the Weakness Break, include characters with Fire-type AoE or random consecutive attacks.

Himeko	Asta	Trailblazer (Fire)
Blast/AoE Follow-up attacks	Random consecutive attacks DMG Buff	AoE *Not available in storyline

Physical Trailblazer Team Build

Physical Trailblazer	Himeko	Asta	Natasha
DPS Single target/AoE	DPS Fire-type AoE	DMG Buff Toughness DMG	Healer Debuff Remover

A team centered on the Physical Trailblazer, who is available from the beginning. He can be used for single-target attacks and AoE, depending on the situation. Paired with Himeko and Aster, who can exploit weaknesses in every part of the enemy's body, allowing you to trigger the Weakness Break frequently. Additionally, Natasha's skills can remove Quantum Entanglement and Imprisonment.

Storyline Team

Physical Trailblazer	March 7th	Dan Heng	Himeko
DPS Single target/AoE	Shielder *Cannot inflict Frozen	DPS Inflicts SPD Debuff	DPS *For Trial

For the first encounter with the boss, most people will be using these characters. Keep attacking with Physical Trailblazer, Dan Heng, and Himeko (Trial). As the enemy doesn't deal high damage in the first encounter, it is possible to finish it without a Healer by simply applying March 7th's Shield at pivotal moments.

Doomsday Beast Battle Walkthrough

1. Defeat One Hand (Right Hand) First

Each part of the Doomsday Beast has its own HP and acts at every turn. The Antimatter Engine boosts both hands and unleashes a potent AoE, and its durability is high, so it is recommended to target the right hand of the Doomsday Beast first, which has low durability and inflicts Imprisonment on all targets.

2. Attack The Remaining Hands And Engine

Once one of the hands is destroyed, use random consecutive attacks or blasts to defeat the remaining hands and engine. After that, focus on reducing the main body's HP to zero in one turn. To maximize your attack, make sure to accumulate enough Ultimate and Skill Points beforehand.

3. Reduce Its HP To Zero When It Is Downed

Once you defeat all the parts and the main body is downed, use single-target attacks like Skill or Ultimate to bring its HP down to zero in one turn. Keep in mind that the main body has no Weakness Type, so Weakness Break won't work. If you fail to defeat it before the next turn, all of its parts will be revived and you'll have to start over.

4. Remove Quantum Entanglement/Imprisonment If Possible

When the hands of the Doomsday Beast attack, there is a chance that it may inflict Quantum Entanglement or Imprisonment. Even though the chance is low, it can limit your actions when you are inflicted. It is recommended to have a debuff remover on your team to quickly remove it.
