A new Genshin Impact Version 7.2 leak claims to show the full Refinement 1 passive and upgrade costs for Mitya's signature catalyst. The alleged five-star weapon keeps the previously reported 542 Base ATK and 88.2% CRIT DMG stat line, but the new graphic adds an Elemental Skill trigger, stacking Elemental Mastery and a bonus tied specifically to Star-Superconduct CRIT DMG.
The English infographic appeared in the Seele Leaks Telegram feed at 11:49:31 a.m. UTC on September 22 with credit to X1. AboutSnezhnaya reposted the same graphic at 11:50:28 a.m. UTC and credited Seele. These posts belong to one source chain, not two independent confirmations, and the original X1 material was not available for direct inspection.
HoYoverse has not announced Mitya's playable release, signature weapon or Version 7.2 banner. The figures may come from an unreleased test build and can change before release. The weapon's name is also missing, so the report only describes it as Mitya's signature catalyst.
The leaked passive starts with CRIT DMG and Elemental Mastery
According to the graphic, the passive first increases CRIT DMG by 24%. This appears to be an additional weapon effect rather than the catalyst's 88.2% secondary stat, although the leak does not provide an inventory screen or refinement table that would independently verify the wording.
Casting an Elemental Skill reportedly grants an effect called Formulaic Harmony. The effect gives the wielder 48 Elemental Mastery for 20 seconds. While Formulaic Harmony is active, an Elemental Reaction triggered by a nearby party member gives the wielder one stack of Formulaic Disjunction.
Each Formulaic Disjunction stack allegedly adds another 24 Elemental Mastery. The graphic sets a maximum of three stacks during one Formulaic Harmony period, which would place the reported total at 120 Elemental Mastery once all three stacks are active. That total combines the initial 48 points with 72 points from the stacks.
The reaction condition is important. The infographic says nearby party members can generate the stacks by triggering an Elemental Reaction. It does not say that every reaction must be Star-Superconduct, nor does it explain whether reactions triggered by the wielder count under the same condition. Those missing details could affect how easily the weapon reaches its maximum in different teams.
Star-Superconduct receives a separate CRIT DMG bonus
Formulaic Disjunction has another reported effect when the wielder triggers a Star-Superconduct reaction. Each stack adds 12% Star-Superconduct CRIT DMG, creating a stated maximum of 36% at three stacks.
That clause is narrower than a general CRIT DMG increase. The leak does not say that it boosts all of Mitya's attacks or every reaction. It specifically attaches the bonus to Star-Superconduct CRIT DMG, while the opening 24% CRIT DMG line is presented separately.
The distinction matters for weapon value outside Mitya's intended teams. The large secondary stat, the opening CRIT DMG bonus and up to 120 Elemental Mastery could look broadly attractive, but part of the passive may only reach its full value in a composition that consistently uses Star-Superconduct. The leak does not establish whether another catalyst character could activate every clause, whether the effect works while the wielder is off field or whether Formulaic Disjunction stacks have individual durations.
A final sentence in the graphic says that casting an Elemental Skill removes the existing effects first. If that wording is accurate, recasting the Skill would reset the active Formulaic Harmony period and its accumulated Formulaic Disjunction stacks before applying a new effect. It may prevent players from carrying three stacks into a refreshed 20-second window, but exact rotation advice should wait for gameplay evidence and official wording.
