Proboscis Cernos

Charged bow with tethering appendages and viral explosions

Released Nov 19, 2020

Proboscis Cernos is a charged bow whose arrow impact spawns appendages that pull nearby enemies, followed by explosive damage. Consider it when grouping enemies through the listed pull effect is useful; its low listed critical chance and multi-stage attack make it important to distinguish the arrow from the appendage and explosion entries.

Proboscis Cernos GUIDE

Understand Proboscis Cernos

Useful when…

  • Use the impact-triggered appendages to pull nearby enemies together.
  • Use its separately listed Viral area attacks where the charge and blast behavior suit the encounter.

How do the arrow and appendages work?

The Charged Shot is a projectile with a 0.7-second charge time, dealing 103.23 Impact, 145.08 Slash, and 30.69 Puncture. The Appendages entry is an AoE dealing 49 Slash and 41 Viral, with no falloff reduction listed through 9 m. Charged Shot Explosion is separately listed as an AoE dealing 1003 Viral, with 50% damage reduction by 7 m. Each entry lists 7% critical chance, 1.9× critical multiplier, and 43% status chance. The description says the appendages latch onto nearby enemies and drag them close before bursting; the figures do not establish how many targets are pulled or the exact timing.

What handling and fitting should I plan around?

It has a Charge trigger, one-round magazine, 0.6-second reload, and listed accuracy of about 16.7. Mastery Rank 15 is required. Two Naramon polarities are listed, which can inform compatible mod placement, but no build or final output is specified. Component requirements are listed in its build data, but no drop chance or current acquisition route is established here.

Which bow alternatives serve other purposes?

Nataruk's description emphasizes shots released just before full charge for maximum effect. Lenz is described as an icy pulse followed by a conventional explosion, while Nunchasa's alternate fire launches a charged blizzard arrow that freezes enemies it touches and leaves a chilling path. These have distinct timing or control effects and are not evidence that they reproduce Proboscis Cernos's appendage pull.

Limitations and tradeoffs

  • The low listed critical chance contrasts with its 43% status chance.
  • Charged firing and a single-round magazine impose deliberate shot pacing.

Common mistakes to avoid

  • Do not treat the arrow, appendage AoE, and explosion as one attack with identical damage types.
  • Do not assume the pull affects a fixed number of targets; none is specified.
