Mitya’s unreleased signature weapon is reportedly a five-star catalyst with 542 Base ATK and an 88.2% CRIT DMG secondary stat in Genshin Impact 7.2. AboutSnezhnaya posted the figures on September 17 at 14:01 UTC and credited LoveHappy as the upstream source. The report is unconfirmed and marked subject to change.
The numerical split is the first concrete stat profile attached to the weapon in the source chain inspected for this report. Previous leak coverage had only associated Mitya’s catalyst with a self-focused Elemental Mastery effect, without giving its rarity, weapon class or level 90 attributes. The new post adds those missing basics, but it does not include the weapon’s name, passive description, refinement values, appearance or upgrade materials.
There is one identifiable source chain behind the claim. AboutSnezhnaya’s post was repeated by Seele Leaks roughly ten minutes later, with the same figures and attribution. That repetition is not independent corroboration. LoveHappy’s original item was not available for direct inspection, while the English-language reposts were, so the numbers should be treated as a single-source leak rather than confirmed beta data.
The leaked catalyst favors CRIT DMG over Base ATK
If the figures survive testing, the weapon would reach 542 Base ATK and 88.2% CRIT DMG at level 90. That is a clear low-Base-ATK, high-CRIT-DMG profile for a five-star weapon. It would place a large share of the weapon’s visible stat budget in its secondary stat rather than its attack value.
For players, the immediate appeal is straightforward. An 88.2% CRIT DMG stat can make it easier to build a damage dealer around CRIT Rate artifacts without giving up the chance to reach a strong overall CRIT balance. It does not guarantee a complete build, however. Mitya’s own ascension stat, artifact set, teammates and final passive would still determine how much CRIT Rate or CRIT DMG he needs from artifacts.
The 542 Base ATK figure also needs context. Base ATK contributes to the value of percentage-based ATK bonuses, so a lower value can matter for a character whose damage relies heavily on conventional ATK scaling. A powerful passive, unusual kit conversion or access to other multipliers can offset that tradeoff, but none of those interactions can be calculated from the current post alone.
The leaked numbers therefore describe the weapon’s direction, not its final strength. They suggest a catalyst designed to deliver a very large CRIT DMG stat while leaving more of its identity to the passive effect.
The missing passive is the most important part
Earlier Mitya leaks said his signature weapon would provide a self-focused Elemental Mastery benefit. That remains relevant context, but the September 17 stat post does not restate the passive or explain how the effect activates. It is not yet possible to tell whether the two reports describe the same testing version of the catalyst.
Exact passive wording would answer several questions that the base stats cannot. The effect might grant flat Elemental Mastery, increase it after a particular action, convert another stat into Elemental Mastery, or reward the use of Mitya’s reported summoned units and Polestar Field mechanics. Each possibility would change how the weapon fits his teams and how broadly useful it could be on other catalyst users.
The refinement curve is missing as well. Signature weapons often gain more than one bonus from their passive, and the difference between Refinement 1 and Refinement 5 can reveal which part of an effect HoYoverse expects players to scale. Without those values, any damage comparison against existing catalysts would be premature.
This is also why the leaked 88.2% CRIT DMG figure should not be treated as proof that the weapon will be universally strong. A large secondary stat is attractive, but a narrowly tailored passive can make a signature weapon much better for its intended owner than for the rest of the roster. Conversely, a flexible passive could turn the catalyst into a useful option for several damage dealers. The present leak does not establish either outcome.
