Here’s a list of all of Mydei’s required materials.
Mydei skills and kit
Mydei is a 5-star Imaginary character on the Path of Destruction. His kit revolves around him using up his own HP to deal massive DMG. While this puts him in danger of dying, Mydei’s immortality makes its way onto his kit. As long as he “dies” at the right moment, he can keep fighting.
