Luocha

Luocha is a popular playable character in the game Honkai: Star Rail, known as a mysterious, coffin-carrying foreign merchant with exceptional medical skills who provides powerful, automatic healing and debuff cleansing for his team. He is a top-tier defensive support who excels at keeping allies alive without using skill points, making him highly valuable for difficult content, though newer sustains offer more utility. His kit revolves around his skill, which auto-heals allies below 50% HP, and his talent, which creates a field that heals allies when they attack enemies within it. His auto-healing means he rarely needs to use skill points.
