Mitya is a five-star Electro Catalyst user lined up for the Genshin Impact 7.2 update, and his signature weapon has surfaced through beta leaks. It is a five-star catalyst built to lean into CRIT DMG and Elemental Mastery, which matches his role as a Stellar Conduct damage dealer. Everything below reflects pre-release testing values and can change before launch.
Quick answer: The catalyst reaches 542 Base ATK and 88.2% CRIT DMG at level 90, and its passive layers CRIT DMG with stacking Elemental Mastery tied to Elemental Skill casts and reactions.
Mitya signature catalyst stats at level 90
The weapon carries a low attack value and puts most of its budget into its secondary stat. That heavy CRIT DMG stat makes it easier to chase CRIT Rate on Mitya’s artifacts while keeping a balanced crit ratio.
| Attribute | Value (Lv. 90) |
|---|---|
| Rarity | 5-star Catalyst |
| Base ATK | 542 |
| Secondary stat | 88.2% CRIT DMG |
Weapon passive effects at R1
The passive adds a flat CRIT DMG bonus and a reaction-driven Elemental Mastery engine. Casting an Elemental Skill starts the buff window, and party reactions feed extra stacks that scale up during that window.
- CRIT DMG increased by 24%.
- Casting an Elemental Skill grants “Formulaic Harmony,” raising Elemental Mastery by 48 for 20 seconds.
- While “Formulaic Harmony” is active, a party member triggering an Elemental Reaction grants a stack of “Formulaic Disjunction.” Each stack adds 24 Elemental Mastery.
- A triggered Stellar Conduct reaction adds 12% to Stellar Conduct CRIT DMG for every stack.
- Up to three “Formulaic Disjunction” stacks can build during one “Formulaic Harmony” period. Casting the Elemental Skill again clears the existing effects.
The passive resets when you recast the Elemental Skill, so stack timing follows Mitya’s rotation rather than running indefinitely.
Ascension materials to level the weapon
Bringing the catalyst to level 90 pulls from a domain drop line and a Snezhnaya enemy material, plus a new enemy drop that scales across three rarities. The full requirement is listed below.
| Material | Quantity |
|---|---|
| The Frost Emperor’s Revival | 5 |
| The Frost Emperor’s Ceremony | 14 |
| The Frost Emperor’s Lament | 14 |
| The Frost Emperor’s Farewell | 16 |
| Ethereal Glimmershard | 15 |
| Ethereal Crystal | 23 |
| Ethereal Crystalscale Stone | 27 |
| New enemy drop | 23 / 27 / 41 |
You can farm The Frost Emperor’s Revival and its higher rarities in the Scars of Cursed Obsession domain, available on Wednesday, Saturday, and Sunday. Ethereal Glimmershard and its upgraded forms drop from Snowland Fae enemies in Snezhnaya, and they can also be bought from Paimon’s Store.
Why the stat line fits Mitya
Mitya scales off Elemental Mastery and centers his damage on the Stellar Conduct reaction, the Cryo and Electro pairing built up in Snezhnaya. The weapon’s stacking Elemental Mastery feeds that scaling directly, while the CRIT DMG stat and passive cover his personal hits without leaning hard on outside buffs.
His Elemental Skill has tap and hold versions that lock in an on-field or off-field mode when cast. The on-field tap is treated as his main seat, reshaping the Polestar Field into Stellar Conduct reaction damage, while the hold mode applies Electro and Stellar Conduct hits from the bench, closer to a Yae Miko style.
Because the weapon buff hangs on Skill casts and reaction stacks, rotation length matters. A short skill press favors quick clears, while a longer press pushes total damage, so how often you recast changes when the passive resets and rebuilds.
Release window and what remains uncertain
Mitya is expected to debut in Version 7.2, with an unofficial banner estimate around early November 2026. HoYoverse has not confirmed his banner date, his kit, or this catalyst, and no official next date is locked in yet.
Treat the stats, passive wording, and material counts as beta values. Numbers and effects can shift during testing, so hold off on planning artifacts or spending until the weapon appears on a live weapon banner.
