Vesper 77

Semi-automatic precision secondary

Released Dec 13, 2024

Vesper 77 is a semi-automatic hit-scan pistol whose laser sight highlights weak points; aiming increases its critical damage multiplier. Consider it when you can aim deliberately and exploit weak-point shots, rather than when you want a high-capacity automatic sidearm.

Vesper 77 GUIDE

Understand Vesper 77

Useful when…

  • Deliberate weak-point and headshot aiming.
  • Players who prefer powerful individual shots and can work within an eight-round magazine.

Handling and weak points

The Vesper 77 fires one hit-scan shot per trigger pull, with a listed fire rate of about 2.08 shots per second. Its laser sight highlights enemy weak points, and aiming increases its critical damage multiplier; the size of that increase is not specified. The base critical chance is 24% and base multiplier 2.6×, so aiming into the highlighted weak point is central to its described precision use.

Damage and capacity

Each normal hit-scan shot has 180 base damage, split between Impact and Puncture, with 26% status chance. The eight-round magazine and 2.35-second reload favor measured shots over continuous fire. Its accuracy stat is 16, and no alternate fire or other attack mode is listed.

Build and alternatives

It requires Mastery Rank 14 and has Madurai and Naramon polarities. A build can use matching polarity mods; prioritizing weak-point accuracy and critical damage is consistent with its stated aim bonus, but the exact bonus and build outcome are not given. Athodai Prime also rewards weak-point kills, but those kills trigger a temporary fire-rate and infinite-ammo Overdrive. Coda Pox is a thrown weapon, while Coda Tysis is a pistol; their descriptions emphasize different forms and do not establish them as direct replacements.

Limitations and tradeoffs

  • The small magazine and semi-automatic trigger demand shot pacing and reload management.
  • Its weak-point benefit depends on aiming; the magnitude of the multiplier increase is unspecified.
  • The weapon description does not state any silencing mechanic despite the internal weapon category name.

Common mistakes to avoid

  • Treating the weak-point critical multiplier increase as a fixed known amount.
  • Firing continuously without accounting for the eight-round magazine and reload time.
