Team Composition & Strategy Tips

Use Daisy for Petrify Immunity & Buff Removal

Since Mercure applies Petrify, Petrify Immunity is a must. Additionally, Buff Removal is also necessary to strip Mercure's Barrier. Daisy, who possesses both of these, is essentially required.

Remove the Barrier with Buff Removal

Mercure applies a Barrier with Skill 1. Remove it immediately using Buff Removal from Daisy, Biscuit, or similar heroes. If the skill CT doesn't line up in time, using buff turn reduction from Miho is also an option.

Manage HP through Heals and Barrier

Heroes with Barrier and Heal

Shield & Barrier Heroes
Daisy	Xiao Qiao	Melia	Evan
Asura	Rook

Heal & HP Recovery Heroes
Pallanus	Lina	Sun Wukong	Reginleif
Alice	Yui	Lucy	Lee Joohee
Bai Jiao	Diaochan	Karon

Since Mercure applies Magic Reflux, your HP will continuously be depleted. Manage your HP using Healers like Lina and Sun Wukong, or Barriers from Evan. The healing and Debuff Removal from Reginleif's Magic 5-hero formation effect is also effective.

Tips!	Lucy does not have Continuous Healing, but her strength lies in being able to reduce the number of Magic Reflux stacks with 3 Debuff Removals.

Shane or Pascal Is Best as an attacker

Since there is only one enemy, use a single-target attacker like Shane or Pascal. When using Reginleif, Pascal is recommended to activate the Magic 5-hero formation effect.

Best Team & Pets

Party Example with Sun Wukong

Front Row	Front Row	Front Row	Front Row	Back Row
Biscuit	Lina	Daisy	Sun Wukong	Shane

This is a party example that uses Sun Wukong as a secondary attacker and Healer. This slot can be swapped with Alice, Lucy, Evan, or others. If Pascal is better developed than Shane, swapping them out is also fine.

Roles and Best Equipment

Hero	Reason for Use	Recommended Equipment
Biscuit	- Buff/Debuff - Buff Removal	Gatekeeper x Revive Ring
Lina	- Healer - Buff/Debuff	Paladin x HP or Revive Ring
Daisy	- Petrify Immunity - Buff Removal	Gatekeeper x Revive Ring
Sun Wukong	- Attacker / Healer	Avenger x Boss Ring
Shane	- Attacker	Avenger x Boss Ring

Reginleif Party Example

Front Row	Front Row	Front Row	Front Row	Back Row
Reginleif	Daisy	Miho	Xiao Qiao	Pascal

This is a party example that counters Magic Reflux using Reginleif's Magic 5-hero formation effect for HP healing and Debuff Removal, along with Barriers from Daisy and Xiao Qiao, while attacking with Pascal. This party is recommended if Pascal is well developed.

Roles and Best Equipment

Hero	Reason for Use	Recommended Equipment
Reginleif	- Debuff - HP Heal - Debuff Removal	Gatekeeper x Revive Ring
Daisy	- Sub Attacker - Petrify Immunity - Buff/Debuff - Buff Removal - Barrier	Gatekeeper x Revive Ring or Avenger x Boss Ring
Miho	- Buff/Debuff - Debuff Removal	Gatekeeper x Revive Ring
Xiao Qiao	- Sub Attacker - Buff/Debuff - Debuff Removal - Barrier	Gatekeeper x Revive Ring or Avenger x Boss Ring
Pascal	- Attacker	Avenger x Boss Ring

Recommended Pets

Recommended	Alternative (Legendary)	Alternative (Rare)
Windy	Eirin (When using Shane) Yeonji (When using Pascal)	Sherry (When using Shane) Note (When using Pascal)

Since the opponent is a single boss, Windy is the most recommended pet. If you don't have Windy or haven't developed her, Eirin is recommended if your attacker is Shane, and Yeonji if your attacker is Pascal.

Party Examples for 6 Medals

The party examples above are intended for players aiming for 6 medals. If you want to reduce the medal count, you can broaden your formation options — for example, since Petrify Immunity becomes unnecessary, you could run a 2-attacker composition with both Pascal and Shane, or include Kyle if he is more developed.
