In The Storyline, Trailblazer Is A MUST In The Battle

In the storyline, Trailblazer (Physical) is a required team member to face Cocolia, Mother of Deception. Trailblazer (Fire) will replace the physical version in the second half of the battle, but if you're struggling in the first half, it's recommended to enhance Trailblazer before taking it on.

Use AoE With The New Mechanic

In the battle against Cocolia, the "Engine of Creation" is a new mechanic where the character's Energy builds up when allies attack and get hit, similar to the character's Ultimate.

Activating it causes a powerful AoE attack, and it is possible to inflict the "Weakness Break" to "Lance of the Eternal Freeze." It is recommended to use it to reduce Toughness when Cocolia summons or uses powerful attacks.

Can Be Rematched In Echo of War After Completing Jarilo-VI

Defeating Cocolia, Mother of Deception, in the storyline will unlock her as an enemy in Echo of War. This play mode allows players to battle enhanced chapter bosses and earn 4-star Light Cones and exclusive Trace upgrade materials.

The Rewards Are Required For Some Characters' Trace Enhancement

To enhance certain characters, you need unique materials, which can only be obtained in Echo of War three times weekly. Since you need a lot of materials, we recommend challenging Echo of War each week after it is unlocked.

Tips To Team Up

DPS With Fire, Lightning, Or Quantum Type Is Highly Recommended

Cocolia, the Mother of Deception, is resistant to Physical, Ice, Wind DMG, and Frozen and Imprisonment debuffs. However, she has three weaknesses: Fire, Lightning, and Quantum.

If you can trigger a Weakness Break, you can prevent Cocolia's powerful attacks. Quantum Entanglement, in particular, delays Cocolia's Action Order, so it is recommended to include characters with Weakness Types, especially Quantum.

Frozen/Imprisonment Removal Ability Is Also Required

Cocolia, Mother of Deception, periodically inflicts Frozen/Imprisoned on a single ally. Shield and Effect RES cannot prevent this debuff. It is advisable to have a preparation to remove the debuff.

Characters with Debuff-Removal Skills

Seele's Action Boost Team

Removes Debuff
Reduces Toughness
Removes Debuff

The core of this team is the Quantum DPS, Seele, who can act many times and excels in DMG and Toughness-reduction.

When defeating the summoned "Lance of the Eternal Freeze," her Talent allows her to increase DMG and receive an extra action. Combined with Bronya's skills, she can act four times in one turn.

Also, the two debuff removers make it difficult to be defeated by Frozen or Imprisonment.

Jing Yuan Weakness Break Team

The team specializes in Weakness Break, with Jing Yuan and Asta, who are good at reducing Toughness.

Jing Yuan's attacks are mainly AoE, making it easy to handle "Lance of the Eternal Freeze." Depending on Tingyun's Ultimate target, you can choose buffs between DMG boost, Recovery, or SPD Boost.

F2P/Dolphin Team

Reduces Toughness
Removes Debuff

This team mainly consists of regular 4-Star characters that are easy to obtain for players who spend little or no money.

The main DPS, Hook, deals moderate damage but has high durability due to her self-healing ability and the additional effect, "Naivete," which prevents the Frozen and Imprisonment with a probability.

How To Defeat Cocolia, Mother of Deception

1Aim for Weakness Break
2Use "Engine of Creation" to handle weaker enemies
3Keep HP as high as possible
4Remove Frozen/Imprisonment quickly

1. Aim For Weakness Break

Cocolia, Mother of Deception, inflicts high DMG and Crowd Control debuff in both phases. You should delay her action with Weakness Break and use attacks of the Weakness Types for a quick defeat.

2. Use "Engine of Creation" To Handle Weaker Enemies

In the first half of the battle against Cocolia, Mother of Deception, she will periodically summon weaker enemies. The summoned "Lance of the Eternal Freeze" will repeat AoE attacks, so use the "Engine of Creation" mechanic with Weakness Break to quickly defeat them.

3. Keep HP As High As Possible

Cocolia, Mother of Deception, can inflict high DMG and Crowd Control debuffs that prevent Healers and Shielders from acting, often resulting in allies being defeated. It is crucial to keep the HP of all allies as high as possible, especially if your characters aren't very strong.

4. Remove Frozen/Imprisonment Quickly

Cocolia, Mother of Deception, frequently inflicts Frozen or Imprisonment debuffs. Effect RES is not effective in preventing these debuffs. If you have a debuff remover in your team, be careful not to drop to 0 Skill Points and remove the debuffs as soon as possible.

Also, it is recommended to include characters with Taunt to prevent the Healer from being Frozen or Imprisoned.
