Intro
Character Summary

Mosin-Nagant is a long-range, single-target damage dealer with little to distinguish her beyond the general traits common to all rifle users (such as long range) and the synergies available to her as an Electric elemental damage dealer (e.g., pairing with element-specific buffers or debuffers like Lenna). Her straightforward and unremarkable kit lacks a distinct identity, and the absence of a clear niche leaves her in want of purpose.

Fixed Keys

Fixed Keys core to Mosin-Nagant’s function are:

  • N/A: Mosin-Nagant does not have any Fixed Keys that meaningfully boost her performance or redefine her role as a character.

Mod Key

Mosin-Nagant doesn’t have a Mod Key available yet.

Character Function

Mosin-Nagant serves primarily as a barebones single-target damage dealer, with few redeeming qualities. Her performance is hindered by significant kit issues, including:

  • For an elemental damage dealer, Mosin-Nagant’s physical-to-elemental damage distribution is poor. Unlike other elemental damage dealers with more functional kits (e.g., Makiatto), Mosin-Nagant’s skills deal Physical damage, with her S2 providing a self-buff (Active Engagement) that converts her next attack to Electric damage.

  • Her Action Support is highly conditional, requiring Stability Break to trigger, making it nearly impossible to proc on-demand. This results in poor single-target consistency, which barely adds to her already underwhelming damage output. 

  • Mosin-Nagant’s Confectance Index gain depends on her Action Support procs, which severely restricts her resource generation. In longer stages, her consumption often outpaces her ability to replenish it.

Character Synergies

SSR characters are typically assessed at V0/V1 strength, but Mosin-Nagant’s synergy is discussed based on her V6 performance, as much of her kit’s effectiveness is gated behind later dupes. To briefly cover the Mosin-Nagant (V6) - Andoris - Belka team:

  • Mosin-Nagant’s V4 automatically triggers her Active Engagement self-buff with every support attack. Her V6 improves the proc condition, allowing it to trigger when Electric debuffs are applied. This upgrade increases her damage potential significantly, with her passive delivering a total damage multiplier of 330% (110% per proc, 3 procs per turn).

  • Andoris and Belka play a crucial role in enabling Mosin-Nagant’s (V6) passive, applying the Negative and Positive Charge debuffs to trigger her Wise Support. 

  • Lenna (and Lenna’s Common Key) can fulfill a similar role but with a lower damage ceiling; Lenna’s Electric debuffs are more oriented towards crowd control rather than maximizing damage output.

Vertebrae Breakpoints

SSR characters are reviewed at V0/ V1 strength. However, for those especially dedicated players, it is worth noting Mosin-Nagant’s significant dupe powerspikes at:

  • V4: Mosin-Nagant's V4 changes her Action Support damage type to Electric, allowing her to fully leverage Andoris and Belka's powerful Electric damage buffs and debuffs.

  • V6: Wise Support now triggers from the application of Electric debuffs, simplifying the proc condition and greatly enhancing her performance, bringing her in line with other top-tier damage dealers. (At the cost of 6 dupes)

Pros & Cons
Pros

  • Long Range

  • Applies Paralysis, stops enemies from attacking resulting in a great source of Crowd Control.

Cons

  • Highly conditional Action Support trigger severely limits its effectiveness.

  • Dependence on Action Support for Confectance Index gain all but guarantees shortages.

  • Requires dupes to be competitive with alternative damage dealers.

  • Paralysis does not apply to bosses, making it completely useless outside of mobbing.

Ratings

For Global tier list, both SR and SSR characters are rated at V0 (no dupes). For CN tier list, SSR characters are rated at V0 (no dupes) and SR characters are rated at V6 (max dupes).
