Genshin Impact’s Mika is a four-star cryo support who wields a polearm. His unique and diverse kit allows him to heal his allies, which also buffing their physical damage and increasing their attack speed.
Mika’s best weapon is Favonius Lance, and his top artifact set is Noblesse Oblige. He requires quite a lot of energy recharge, but also benefits from HP. And, if you equip him with Favonius Lance, he needs a bit of crit rate, too.
Mika’s healing scales with HP so, while he’s generally sufficient at level 80, you can choose to get him to level 90 if you want to boost his heals further.
When leveling up his skills, you should generally prioritize his elemental skill first, then his elemental burst, though both are important so it’s good to level them up simultaneously. His normal attack isn’t worthwhile, so don’t worry about leveling it unless you want to.
Mika is generally recognized as a dedicated support for Genshin Impact’s Eula, as his kit compliments physical DPS. However, he can also play a role in a team with Genshin Impact’s Wanderer and Genshin Impact’s Faruzan.
How to use Mika
Mika’s personal damage is negligible, and isn’t worth your time and investment. As you may expect, where he really shines is through his ability to support his team.
His skill provides a strong attack buff and generates four cryo particles, but provides very low cryo application and has a 15 second cooldown. The attack buff from the skill lasts for 12 seconds, and its effect scales with his skill’s talent level, which is why you should prioritize upgrading it.
The tap version of his skill fires in a straight line, which makes it hard to hit multiple enemies. Generally, we recommend using the hold version instead – just keep in mind that it can’t hit the same enemy twice.
Mika’s elemental burst starts with a team-wide heal, then applies healing over time for the on-field character whenever they hit enemies with normal attacks. Keep in mind that charged and plunging attacks don’t trigger these heals, and his burst doesn’t deal damage or apply cryo – it’s entirely support-focused.
The interval between each instance of healing is pretty long, and it can trigger a maximum of six times. Luckily, it has pretty good multipliers, so it can still restore plenty of HP for your on-field character if you’ve invested enough into your Mika.
All that said, there’s not much to Mika’s rotations or combos – use his burst to top up team health, and use the hold version of his skill to provide your DPS with a healthy attack boost before they take to the field. It’s as simple as that!
What are the best weapons for Mika?
The best weapons for Mika revolve around boosting his energy recharge so you have more room to focus on HP in his artifacts. Our top recommendation is Favonius Lance, as it boosts his own energy recharge and helps him battery his team. Mika can struggle to proc its passive, especially if he doesn’t have enough crit rate, but it remains his best-in-slot regardless.
Alternatively, any energy recharge main stat weapon is a good choice – if you’re struggling for options, you can even equip him with the craftable Prototype Starglitter as a pure stat stick.
If you manage to get Mika to his energy recharge requirements through artifact substats, you can also try Black Tassel, which increases his healing through its HP stat.
| Weapon | Effect | How to obtain |
| Favonius Lance | Base stat: energy recharge Skill: crit hits have a 60% chance to generate a small amount of elemental particles, which regenerate six energy for the character. This can only occur once every 12 seconds |
Gacha |
| Prototype Starglitter | Base stat: energy recharge Skill: after the equipping character uses an elemental skill, increases their normal and charged attack damage by 8% for 12 seconds. Max two stacks |
Forge via blacksmith |
| Black Tassel | Base stat: HP Skill: increases damage against slimes by 40% |

What are the best artifacts for Mika?
Mika makes for a great Noblesse Oblige holder due to its strong, team-wide buffing capabilities. However, keep in mind that the four-piece set’s buff doesn’t stack, so if you already have someone on the team holding Noblesse Oblige, it’s better to go with something else.
Alternatively Ocean-Hued Clam is a viable option for Mika. Due to his teamwide healing being tied to his burst and his physical damage buffs not affecting Ocean-Hued Clam’s damage, Mika can’t maximize this set’s potential as well as other healers.
However, if you plan on putting him in a superconduct team or pairing him up with Eula, the resulting physical resistance shredding from superconduct reactions and Eula’s held skill does trigger the set’s four-piece bonus, making it a far more effective choice – though Noblesse Oblige still beats it out in most situations.
Finally, the four-star set The Exile is a decent option as it offers benefits to the rest of his team. The main issue is that, as it’s a four-star set, it caps at a lower level that its five-star alternates, and that can be an issue for our stat-hungry boy. Therefore, we recommend you only use this set if you have nothing more suitable.
| Artifact set | Effect | How to obtain |
| Noblesse Oblige | Two equipped: elemental burst damage +20% Four equipped: increases all party members’ attack by 20% for 12 seconds after using an elemental burst. This effect cannot stack |
Clear Pool and Mountain Cavern domain, Minlin, Mt. Aozang |
| Ocean-Hued Clam | Two equipped: healing bonus +15% Four equipped: upon healing a party member, a foam appears, accumulating healed HP for three seconds. The foam then explodes and deals 90% of the HP healed as damage to nearby enemies. Max accumulated healing is 30,000 HP, including over-heal. There can only be one foam active at a time, but it remains even if the character leaves the field. Foam cooldown is 3.5 seconds |
Slumbering Court domain, Fort Hiraumi, on Seirai Island |
| The Exile | Two equipped: energy recharge +20% Four equipped: using your elemental burst regenerates two energy for all party members (excluding the wearer) every two seconds for six seconds. This effect cannot stack |
Opening chests, defeating enemies, etc. |
Artifact stat recommendations
First and foremost, you should focus on meeting Mika’s energy recharge requirements.
As a base rule, with between zero to three constellations, he needs about 180-220% energy recharge to be able to burst in every rotation. At C4 or higher, this drops to around 160-180%. This is a rough estimate, so if you want a more specific number, you can check out this community-made Energy Recharge Calculator.
Outside of that, you can primarily focus on HP to boost his healing. If your Mika is using Favonius, you can also go for a crit rate circlet or aim for some extra crit rate substats to help trigger its passive more reliably.
Main stats:
- Sands – energy recharge or HP%
- Goblet – HP%
- Circlet – crit rate (if using Favonius) or HP%
Sub-stats:
- Energy recharge (to requirements)
- HP%
- HP
- Crit rate (if using Favonius)
What are the best Mika team comps?
As a healer and buffer, Mika can slot into many different team comps. However, to make the best use of him, we recommend using him as a physical DPS support or an attack speed buffer.
As a physical DPS support, we’d be remiss to leave out Eula, as his kit appears to be tailored specifically to support her. However, as Mika doesn’t provide physical resistance shred and his cryo application is pretty low, it’s worth filling the other two slots with an off-field electro unit and another cryo character.
For a team where Mika focuses on buffing attack speed, we recommend pairing him with Wanderer, along with another anemo to help keep Wanderer’s energy up, and Bennett for the extra attack buff.
Here are two example team comps. Click on the character icon to open their full build in a new tab.

What are Mika’s abilities?
Here are all of Mika’s abilities and talents.
Mika active talents
| Skill | Description |
| Normal attack: Spear of Favonius – Arrow’s Passage | Normal: perform up to five consecutive strikes using Mika’s crossbow and spear Charged: consume a set amount of stamina to lunge forward, dealing damage to opponents along the way Plunge: plunge from mid-air to strike the ground below, dealing damage to opponents along the path and dealing AoE damage on impact |
| Elemental skill: Starfrost Swirl | Mika uses his crossbow to attack, granting all nearby party members Soulwind. When characters in the Soulwind state are on the field, their attack and speed increases. Starfrost Swirl takes effect in different ways if you tap or hold. Tap: fire a Flowfrost Arrow that can pierce through opponents, dealing cryo damage to any enemies it comes into contact with. Hold: go into aiming mode, locking onto an opponent and firing a Rimestar Flare at them, which deals cryo damage. When the Rimestar Flare hits, it rises then explodes, launching Rimestar Shards that deal cryo damage into a maximum of three other opponents |
| Elemental burst: Skyfeather Song | Mika spurs on his teammates, regenerating their HP based on his own max HP, and granting them the Eagleplume state. When an active character affected by Eagleplume hits an opponent with their normal attack, Mika regenerates their HP based on his max HP at set intervals. |
Mika passive talents
| Skill | Description |
| Demarcation | Display the location of nearby resources unique to Mondstadt on the mini-map |
| Suppressive Barrage | Soulwind state grants characters the Detector effect in the following situations: – If the Flowfrost Arrow hits more than one opponent, each additional opponent hit generates one Detector stack – When a Timestar Shard hits an opponent, it generates one Detector stack (each Rimestar Shard can trigger this effect one times) The Detector effect increases the character’s physical damage by 10% per stack when they’re on the field. The Soulwind state can have a maximum of three Detector stacks, and if Mika casts Starfrost Swirl again during this duration, the pre-existing Soulwing state and all its Detector stacks clears. |
| 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 grants them one stack of Detector from Suppressive Barrage. During a single instance of Soulwind, you can gain one Detector stack in this manner. Additionally, the maximum number of stacks that you can gain through Soulwind alone increases by one |
What are Mika’s constellations?

| C2: Companion’s Ingress | When Starfrost Swirl’s Flowfrost Arrow first hits an opponent, or its Rimestar Flare hits opponents, it generates one Detector stack from the passive talent ‘Suppressive Barrage’ |
| C3: Reconnaissance Experience | Increases the level of Skyfeather Song by three, to a max level of 15 |
| C4: Sunfrost Encomium | When Mika’s own Skyfeather Song’s Eagleplume stat heals party members, he restores three energy. This can occur five times during the Eagleplume state from one Skyfeather Song |
| C5: Signal Arrow | Increases the level of Starfrost Swirl by three, to a maximum of 15 |
| C6: Companion’s Counsel | The maximum number of Detector stacks that Starfrost Swirl’s Soulwind can gain increases by one. Additionally, active characters affected by Soulwind deal 60% more physical crit damage |
