Rhea, in her transformed state as Seiros, serves as a major boss in the Crimson Flower route. She is a powerful dragon with immense strength, defense, and resistance. Her attacks have wide ranges and can inflict status effects. Similar to the Immaculate One, focus on units with effective damage against monsters and powerful Combat Arts. Utilize gambits to break her armor and stun her, creating openings for your strongest attackers. Be prepared for a long and challenging battle, and ensure your healers are well-positioned.
