4. Defeat Sunday

For your second encounter with Sunday, the fight will have three phases instead of a single phase. Sunday's elemental weakness are Fire, Lightning, and Imaginary. Bring an AoE character for this fight with the mentioned elements.

The fight will mostly focus on reducing Sunday's toughness bar. Bringing a character like Ruan Mei is a good idea since she can increase Break Effect for the team.

Huohuo and Luocha are also recommended for the cleanse and healing they provide. If you're F2P, consider using Serval, Asta, and Lynx alongside Harmony Trailblazer.
