Diona vs Mika
Defensive utility queen vs. Physical support specialist
TL;DR — Quick Pick
Pick Diona if…
- In almost any team needing a general-purpose defensive unit
- For Freeze or Melt teams that don't care about Physical DMG
- When you need a reliable Cryo battery with Favonius or Sacrificial
Pick Mika if…
- Exclusively in Physical damage teams (Eula/Razor/Freminet)
- If you need an instant team-wide heal to counter Furina's drain
- When ATK speed is a critical factor for your carry
Diona is a far superior generalist with her shield and energy generation. Mika is highly specialized for Physical teams and struggles to provide value in other compositions.

Shared Team Members
With Diona
Diona acts as Eula's primary battery, using a Sacrificial Bow to generate double the Cryo particles needed to fuel Eula's expensive 80-cost Burst. Her shield provides necessary interruption resistance during Eula's 'Lightfall Sword' stacking sequence, while her healing keeps Eula safe in melee range. This pairing is a staple for Eula teams, offering a perfect blend of energy, protection, and sustainability.
With Mika
Mika is Eula's best-in-slot support, providing a massive Physical DMG bonus and an ATK Speed buff that allows Eula to gain more stacks for her Burst. His 'Skyfeather Song' Burst also offers team-wide healing, which is vital for keeping Eula healthy while she builds up her damage. At C6, Mika also provides a 60% Physical CRIT DMG bonus, making Eula's nukes significantly more powerful.
