Dan Heng • Imbibitor Lunae is the five-star Imaginary Destruction character in Honkai: Star Rail, serving as the High Elder of the Xianzhou Luofu and bearer of the Azure Dragon's legacy. He was entrusted with guarding the Ambrosial Arbor, an ancient artifact granting immortality to the Luofu's ancestors. This form is Dan Heng's draconic Vidyadhara transformation, resembling the Astral Express guard Dan Heng but embodying his past power. An outstanding DPS excelling in single-target and AoE damage, he wields immense power through enhanced Basic Attacks, requiring careful SP management. His lore ties deeply to the Vidyadhara lineage and escape from his past.
