Mika — Build, Teams & Rating Genshin 6.7

Is Mika worth building?

Mika is an adorable, fully free 4-star support, but he only truly earns his slot when you run a Normal-Attack Physical carry like Eula, or a fast-hitting DPS who loves Attack Speed. Outside those teams he's pretty niche. The one thing to worry about is enough Energy Recharge to Burst consistently; everything else goes into HP% and Healing Bonus. No premium weapon needed: the Favonius Lance is his best and it's a 4-star. In short, he's fantastic in the right team and safely shelved otherwise.

No talents really need farming — just aim for enough Energy Recharge to Burst on time; put a bit into E for the buff stacks and Q for healing, skip Normal Attacks.

Mika's talents

Spear of Favonius - Arrow's Passage

Normal Attack
Performs up to 5 consecutive strikes using his crossbow and spear.

Charged Attack
Consumes a certain amount of Stamina to lunge forward, dealing damage to opponents along the way.

Plunging Attack
Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.

Starfrost Swirl

Mika uses his crossbow to attack, granting all nearby characters in your party Soulwind. When characters in the Soulwind state are on the field, their ATK SPD will be increased.
Will take effect in different ways if Tapped or Held.

Tap
Fires a Flowfrost Arrow that can pierce through opponents, dealing Cryo DMG to enemies it comes into contact with.

Hold
Goes into Aiming Mode, locking on to an opponent and firing a Rimestar Flare at them, dealing Cryo DMG. When the Rimestar Flare hits, it will rise before exploding, launching Rimestar Shards into a maximum of 3 other opponents, dealing Cryo DMG.

Stars burst 'neath the frosted skies.

Skyfeather Song

Derives the ability to spur his teammates on from the recited prayers of the knightly order, regenerating HP for all nearby party members. This healing is based on Mika's Max HP and will grant them the Eagleplume state.

Eagleplume
When the Normal Attacks of active characters affected by Eagleplume hit an opponent, Mika will help them regenerate HP based on his Max HP.
Characters affected by this state can only regenerate HP in this way once per short interval of time.

"Carry hope when in dire straits, and keep vigil when all is well... For that pure white plume shall at last guide the lost wayfarers."

Suppressive Barrage

Per the following circumstances, the Soulwind state caused by Starfrost Swirl will grant characters the Detector effect, increasing their Physical DMG by 10% when they are on the field.
·If the Flowfrost Arrow hits more than one opponent, each additional opponent hit will generate 1 Detector stack.
·When a Rimestar Shard hits an opponent, it will generate 1 Detector stack. Each Rimestar Shard can trigger the effect 1 time.

The Soulwind state can have a maximum of 3 Detector stacks, and if Starfrost Swirl is cast again during this duration, the pre-existing Soulwind state and all its Detector stacks will be cleared.

Topographical Mapping

When an active character affected by both Skyfeather Song's Eagleplume and Starfrost Swirl's Soulwind at once scores a CRIT Hit with their attacks, Soulwind will grant them 1 stack of Detector from the Ascension Talent Suppressive Barrage. During a single instance of Soulwind, 1 Detector stack can be gained in this manner.
Additionally, the maximum number of stacks that can be gained through Soulwind alone is increased by 1.
You must first unlock the Ascension Talent "Suppressive Barrage."

Demarcation

Displays the location of nearby resources unique to Mondstadt on the mini-map.

Combat Rotation

Identify the role first: Mika is an off-field support/healer (Cryo), not a main DPS.
Cast Elemental Skill (E - Starfrost Swirl, 15s cooldown) to deal Cryo DMG and apply Soulwind, boosting nearby party members' ATK SPD.
Cast Elemental Burst (Q - Skyfeather Song, costs 70 Energy, 18s cooldown) to heal the whole party based on Mika's Max HP and grant Eagleplume.
Swap to your main DPS right away to capitalize on the Soulwind ATK SPD buff and Eagleplume's heal-on-hit.
While your DPS is attacking, wait for Mika's E to come off cooldown (15s) then swap back to refresh Soulwind before it drops.
Return to Mika whenever the 70 Energy is available again to recast Q, refreshing the party heal and Eagleplume.
Prioritize Energy Recharge on Mika so the 70-cost Burst can be reliably recast every rotation.
Pair Mika with attackers who land many hits (bow/polearm/claymore users) to squeeze the most value out of Soulwind.
