Best Team for Ruin 3

Underground Treasure Hunt Day 3 Best Team
Jing Yuan	Tingyun	Bronya	Luocha

Jing Yuan and Tingyun are the trial characters for the Ruin 3 stage. Jing Yuan can benefit from the ruin's Follow-Up Attack boost and Bronya can get his turns faster. When facing enemies mostly weak to Quantum, you can switch him for Seele if you find her in the ruins.

Luocha can be exchanged with Natasha but he is best within the ruins since he has passive healing abilities as well as elemental advantage over one of the elite enemies in the last floor.

You can randomly encounter Bronya in the ruins, but you can also substitute her with a Sub-DPS like Herta or Himeko. Additionally, you may also opt for Clara or Hook, who can also be found in the ruins.
