Mydei is a 5-star character with the Imaginary element on the Destruction path, who fights by spending his own HP, turning every hit he takes into more Charge for his next burst. He’s built around a single gimmick: the longer a fight drags on and the more damage he absorbs, the harder he eventually hits back.

Story and Background: Who is Mydei in Honkai Star Rail?
- Mydei is one of the
- Chrysos Heirs
- , the group of god-candidates competing over Kremnos’s Coreflame of Strife. His own title,
- “the undying Mydeimos
- ,” points at the core of his character: he’s
- a figure defined by dying and coming back, over and over, as part of the price the Heirs pay for their claim
.
That carries straight into his kit, where taking damage and losing HP becomes the actual engine of his powe r, instead of a weakness to play around. He’s relentless, someone who treats near-death as a resource instead of a threat.
Where most Chrysos Heirs are introduced chasing the throne through politics or open combat, Mydei’s introduction leans into how much suffering he’s willing to absorb along the way, fitting for a Destruction path character built entirely around self-sacrifice.
