Mika's best weapons focus on easing his Energy Recharge requirements with Favonius Lance being amazing for that while also helping to support your team by also lowering their Energy Recharge requirements, second to that is Dialogues of the Desert Sages which is less supportive but has the benefit of scaling off of HP %. While Engulfing Lightning tends to be his next best option, it is best saved for other characters such as Raiden Shogun who can better utilise it. Outside of those 3 options, other free options such as Prototype Starglitter and "The Catch" are easily available.

Noblesse Oblige is Mika's best artifact set due to its ability to increase your teams ATK. If someone in the party is already using Noblesse, then Ocean-Hued Clam is your next best thing although it is not as suited.

Mika wants a lot of HP to increase the power of his Healing as well as a Healing Bonus circlet providing a greater benefit than a HP Circlet. CRIT Rate is important to Mika if you are using Favonius Lance so that you are able to provide Energy to the team.

Mika wants around 200-220% Energy Recharge between C1 - C3 however at C4 Mika wants around 160-180% Energy Recharge instead.

Mika's supportive gameplay revolves around his ability to generate Decector stacks which come from his Ascension Passives: Suppressive Barrage and Topographical Mapping . Detector stacks increase your characters Physical DMG by 10% per stack. Mika can generate 3 stacks at C0 and gains additional stacks from his 4th Ascension Passive and his 6th Constellation, for a total of 5 stacks. These stacks can be generated in the following ways:

• Gaining the Soulwind state from using Starfrost Swirl.
• Every additional enemy hit by a Flowfrost Arrow when you Tap his Elemental Skill.
• Every additional enemy hit by a Rimestar Shard when you Hold his Elemental Skill.
• While both Soulwind and Skyfeather Song are active and you CRIT. This is only available once per Soulwind.
• With Companion's Ingress (C2) is active and you attack with Starfrost Swirl.

The Soulwind state is obtained when using Starfrost Swirl, not only is Mika's Elemental Skill incredibly important for the Detector stacks mentioned but the Soulwind state also increases ATK SPD helping to further increase DMG.

Mika's Elemental Skill Skyfeather Song is how he heals the party. After an initial party-wide burst of healing, you will be given an Eagleplume which regenerates HP when your active character deals Normal Attacks. This can occur once every 2.5s/

Mika shines in teams which are able to utilise his Physical DMG buffs or his ATK SPD bufs. He can also be a great healer for Furina, with his party-wide healing being able to help generate Fanfare stacks.

Freminet	Fischl	Xingqiu	Mika

Listed are 2 examples of Physical teams which Mika helps support. The first using Eula as the DPS while having Raiden Shogun for Electro application as well as the Superconduct reaction. Furina helps to provide DMG buffs which more than makes up for the fact that her Hydro application will steal the occasional reaction. The second example instead using Freminet who also uses a Physical playstyle but with the increased Hydro application of Xingqiu due to his ability to benefit from the Shatter reaction.

If you wanted to use Mika in a Physical team which does not use a Cryo DPS, you will want an additional Cryo support such as Rosaria or Shenhe to apply enough Cryo for Superconduct to occur consistently, the buffs and Physical RES Shred they can provide and also the Cryo Resonance gained from using 2 Cryo characters.

Wriothesley	Yelan	Furina	Mika

This is one example of a team featuring Wriothesley which uses Mika. Mika's healing helps both to generate Fanfare stacks for Furina and also to help maintain Wriothesley's HP especially at C0. The downsides however are that he can not effectively use the ATK SPD buff which Mika provides.

Wanderer	Faruzan	Mika	Bennett

Catalyst and Bow users are able to more greatly benefit from ATK SPD buffs such as the ones Mika provides due to not having hitlag on their attacks. In this team Wanderer is able to benefit from these buffs as well as gaining 20% CRIT Rate from Jade-Claimed Flower although it will not be consistent because Mika has infrequent Cryo application. This however means other Cryo characters such as Layla and Rosaria tend to be better in this team.
