Montario Opera House Tips and Strategies

Best Team: Trickster, Masked Dancer, Magic Knight, Assassin

Recommended Characters to Bring
Protagonist			Junah			Hulkenberg			Heismay
Trickster			Masked Dancer			Magic Knight			Assassin

With only a few enemies to face and Louis Guiabern as the primary target, this team is built specifically to handle him.

The Protagonist will focus on debuffing and healing, while Hulkenberg buffs the party and deals damage. Junah's role is to exploit Louis' lack of weaknesses by creating one, while Heismay delivers powerful Dark-based skills.

Team Strategy

Louis will always focus his attacks on the Protagonist and use Royal Coercion, which lowers Attack and Defense. Because of this, the Protagonist will take on a more supportive role, focusing on debuffing Louis with Vidyartha and healing the party with Medicall, inherited from the Savior Archetype.

Since Louis has no natural Weaknesses or Resistances, Junah can use the Thief-Masked Dancer Synthesis Skill, Sable Dance, to give him a weakness to Darkness. This allows Heismay to target Louis with Assassinate for significant damage. Meanwhile, Hulkenberg will deal damage and bolster the team's defense with Marakukaja.
