Yae Miko is an electro catalyst wielder, she is gonna come out in the 2.5 as the newest five-star. along with the 4 stars they are Fischl, Thoma, and Diona. There are no new four stars in this banner sadly but there are two new weapons the Oathsworn Eye and the Kagura’s Verity. The Oathsworn will be free by doing an event in the next update. The Kagura’s Verity will be the best in the slot for Yae Miko and the new five star weapon.
For artifacts, a popular leaker said that the 2 piece Emblem of Severed Fate has a great two-piece bonus for Yae Miko but a 4 piece will also suit her great. The perfect ratio is about a solid 20% ER (Energy Recharge) and 15% Electro damage bonus. The best weapon for her is probably the new weapon that got leaked the Kagura’s Verity. Some 4-star weapons for Yae Miko are the Solar Peral and Sacrificial Fragments. For her attacks, her Elemental Skill is the Yakan Evocation: Sesshou Sakura which makes her drop a Sesshou Sakura that can over time deal Electro Damage to the nearby opponents. As for her Elemtanl Burst the Great Secret Art: Tenko Kenshin she unseals nearby Sesshou Sakuras destroying the outer core and turning them into Tenko Thunderbolts that come from the sky dealing Electro DMG to nearby enemies.
