Using the best build for Fugue in Honkai: Star Rail can thoroughly optimize her as a Super Break DMG support in team comps and effectively increase the damage output the rest of your team is capable of inflicting on enemies. Fugue is the 5-star version of Tingyun which was introduced with Version 2.7. The Fire character follows the Path of the Nihility, which naturally makes her a debuffer, but instead of relying on DoTs, a fully Ascended Fugue in Honkai: Star Rail can reduce enemies’ DEF and help remove their Toughness, making them Weakness Broken for more damage.
