Team Composition & Strategy Tips

Quickly remove the Damage Immunity
- Bai Jiao, Lu Bu, and Kyle are recommended
When HP is low, use a Barrier
- Evan is recommended
Once the immunity is removed, attack with Shane
- Depending on her damage output, a one-shot kill is possible

Remove the Damage Immunity

Sera has a 30-hit Damage Immunity. Use heroes like Bai Jiao, who can inflict Bleed and Poison, or multi-hit heroes like Lu Bu and Kyle to reduce the immunity count and remove it as quickly as possible.

When HP is Low, Use a Barrier

Barrier/Shield Heroes
Rook			Evan			Asura

Due to the additional rule that inflicts Unable to Recover on Basic Attacks, using Heals is difficult. Therefore, use a Barrier when your HP gets low. Evan, with his Defense Boost passive, is highly recommended.

Once the Immunity is Removed, Attack with Shane

Once the Damage Immunity is removed, attack with a Back Row attacker. Since there is only one enemy and the Magical Attack Reduction rule is in effect, a single-target Physical attacker like Shane is recommended. The enemy's durability isn't very high, so a one-shot kill is possible depending on your damage output.

Best Team & Pets

Basic Party Example

Front Row	Front Row	Front Row	Front Row	Back Row
Evan	Bai Jiao	Lu Bu	Kyle	Shane

This is a basic party example where Evan provides durability support, Bai Jiao, Lu Bu, and Kyle remove the Damage Immunity, and Shane attacks. Bai Jiao does not need high damage output, so Spellweaver Equipment, which increases Effect Probability, is recommended.

Roles and Recommended Equipment

Hero	Reason for Use	Recommended Equipment
Evan	- Barrier - Durability buff	Guardian × Defense Ring
Bai Jiao	- Healer - Poison/Bleed	Spellweaver × Resurrection Ring
Lu Bu	- Multi-hit attacker	Avenger × Boss Ring
Kyle	- Multi-hit attacker	Avenger × Boss Ring
Shane	- Main attacker	Avenger × Boss Ring

Recommended Pets

Recommended	Alternative (Legendary)	Alternative (Rare)
Windy	Eirin	Sherry

Since the opponent is a boss, the most recommended pet is Windy. If you don't have Windy or haven't raised it, Eirin, who provides a Physical Attack Boost, is a good alternative.

6-Medal Party Example

The above is a party example for aiming for 6 medals. If you reduce the number of medals, your party composition options expand, as you can include a healer (since Unable to Recover is removed) or a magic attacker (since Magical Attack Reduction is removed).
