Introductions
Welcome to our team composition guide for Mydei in Honkai: Star Rail. In this guide, we'll explore the best teams to build for Mydei, including recommended team compositions, character synergies, and everything you need to know.
Best Synergies for Mydei
Cyrene is one of Mydei's best allies because her Ultimate can trigger his Godslayer Be God while also giving him a strong CRIT DMG boost. This allows Mydei to make better use of one of his strongest attacks while increasing his overall damage.
Tribbie is a great support for Mydei because her buffs directly improve the type of damage he wants to deal. Her DMG increase and RES PEN make Mydei's attacks more powerful, while her own damage gives the team some extra offensive help.
Sunday is a strong alternative if you don't have Cyrene. His Action Advance allows Mydei to take more turns and build up his abilities faster, while his Energy and damage buffs help Mydei use his Ultimate and strong attacks more frequently.
Hyacine is an excellent sustain option for Mydei, especially when paired with Cyrene. Her healing keeps the team alive while her HP-related effects work well with Mydei's HP-focused kit. She can also help Cyrene reach her Ultimate more consistently.
Cerydra can work well with Mydei if you want to focus more heavily on his Skill damage. She provides useful support and works particularly well alongside Cyrene, although Tribbie is generally the easier choice if you have her.
