Physical teams are a somewhat niche play style, but Mika will make them much stronger with very little investment to make him do so. Here’s how you may build this sweet little guy to improve his support capabilities for your teams.
Best Artifacts
Mika is a Support character, so his build focuses on improving his team’s damage and his ability to support them rather than improving his damage.
4-Piece Noblesse Oblige:
Noblesse Oblige is a very useful set for Mikaassuming nobody else in his team is already using it.The2-Piece bonus will increase Elemental Burst damage by 20%which isn’t very useful for Mika as his burst doesn’t actually do any damage. However, The4-Piece bonus will give the party a 20% ATK bonus for 12 seconds every time the character uses an Elemental Burst.This means you’ll want to use Mika’s Elemental Burst as much as possible to keep the ATK bonus active.
Noblesse Oblige’s 4-Piece bonus doesn’t stack, so if you’re playing Mika with a character who already uses a 4-Piece Noblesse Oblige set, you may build him with2-Piece Emblem of Severed Fateand2-Piece Tenacity of the Millelith.

Mika’s Elemental Burst heals characters for an amount that scales off of his HP and as a Support he doesn’t need to do much damage, making him very easy to build.

Best Weapons
As mentioned before, Mika doesn’t need many stats other than HP and Energy recharge to use his Elemental Burst as much as possible meaning he doesn’t need much investment in a weapon either.
Engulfing Lightning
Engulfing Lightning will be a good 5-star weapon for Mika, although he doesn’t particularly need to use a 5-star weapon, so it may be better spent on other characters. Engulfing Lightningat level 90 has a Base ATK of 608 with an Energy Recharge sub-stat of 55.1%.The passive will increase the character’s ATK by 28% of their Energy Recharge over the base 100% to a maximum of 80%.It will alsoincrease Energy Recharge by 30% after using an Elemental Burst for 12 seconds.The ATK bonus of the weapon isn’t very useful for Mika. However, the Energy recharge passive and sub-stat will be extremely useful to help Mika use his Elemental Burst more.
Favonius Lance
Favonius Lance is a 4-star weapon that is very easy to get since you can get it on any banner, it’s also very useful for Mika and any polearm support or Sub-DPS.At level 90 the Base ATK is 565, and it has a sub-stat of 30.6%. The weapon is very easy to refine to rank 5 due to how easy and common it is to obtain. The refinement rank 5 passive gives the character a100% chance to generate additional Elemental Particles once every 6 seconds. This weapon is useful for Mika with its Energy Recharge sub-stat as well as its potential to generate additional Elemental Particles to further improve his Energy Recharge.
Black Tassel
Black Tassel is a 3-star weapon making it even more common than Favonius Lance.At level 90 the Base ATK of Black Tassel is 354, and it has an HP sub-stat of 46.9%, it is one of the few polearm weapons with an HP sub-stat and is useful for Mika’s HP scaling healing. The passive simplyincreases damage against Slimes. The HP sub-stat may be useful, but Mika will needat least 180 Energy Recharge, so you may need an Energy Recharge sands.

Best Teams
As mentioned before, Mika is a dedicated support to Physical teams and the best Physical DPS character is Eula. In this team, Raiden Shogun provides Electro application totrigger Superconduct and decrease Physical Resistancewhile alsoimproving the damage of Eula’s Elemental Burst.Xinyan will provide aPhysical Damage bonus of 15% with her 4th Ascension passive and a Physical Resistance shred of 15% if you have her Constellation level 4.Meanwhile,Mika will provide more Physical Damage buffs with his 1st Ascension Passive and Healing with his Elemental Burst(as well as ATK bonus if he’s built with Noblesse Oblige) HisElemental Skill’s ATK speed increase will also help Eula to build more Lightfall Sword energy stackswhich will increase the damage of her Elemental Burst.
