Mydei 
Destruction Kremnos, the mist-shrouded city of chaos and war! Its royal lineage is tainted with patricide, and its god bears the name of calamity. The undying Mydeimos, the lion apart from the rest. Chrysos Heir who seeks the Coreflame of Strife, must suffer a thousand deaths, be bathed in blood on the path home, and bear the madness of fate alone. — Kingslayer be king, godslayer be god. Iron-hooves pound across the wilderness for the campaign, and must eventually soak in the blood of their homeland.

F2P Mydei (Remembrance Trailblazer / Pela / Lynx)
Overview: A free-to-play friendly Mydei team that uses Remembrance Trailblazer for CRIT/True DMG buffs and turn advance, Pela for DEF shred, and Lynx for Max HP and increased targeting to enable Mydei's HP-scaling kit.
Abundance-buffed Mydei (Cyrene / Cerydra / Hyacine)
Overview: This team centers on Abundance buffers (Cyrene + Cerydra) to maximize Mydei's damage. Use Hyacine as the Chrysos Heir sustain to boost Mydei's HP. If Cyrene is unavailable, other Abundance or strong healers (Luocha, Gallagher, Lingsha) are recommended.
Mydei As Sub-DPS (Castorice / Tribbie / Gallagher)
Overview: Use Mydei as a Sub-DPS to intentionally consume HP and build Newbud for Castorice's Ultimate. Tribbie buffs both damage dealers, and Gallagher provides sustain through Besotted healing. Swap in other supports/healers as needed to balance turn control and survivability.
