For the Helminth Charger mod, see Proboscis.

Each arrow spawns a swarm of sticky appendages on impact. These tongue-like probes latch onto nearby unfortunates and drag them close before bursting into a mess of diseased goo.

The Proboscis Cernos is an enhanced InfCernos.png Mutalist Cernos that launches appendages that pulls enemies in towards its zone of impact before releasing a large DmgViralSmall64.png Viral explosion.


This weapon deals primarily DmgViralSmall64.png Viral and DmgSlashSmall64.png Slash damage.


  • High DmgSlashSmall64.png Slash and DmgImpactSmall64.png Impact damage – effective against health and shields.
  • Third highest status chance of all bows, behind AsymmetricBow.png Daikyu and InfCernos.png Mutalist Cernos.
  • Arrows explode in a 7 meter radius after 1.7 seconds on impacting a surface or enemy.
    • Impact releases appendages that stuns and pulls all enemies within 9 meters towards the impact zone.
      • Appendages tick damage twice on all affected enemies before exploding.
      • Ticks do 90 damage, with a distribution of 56.25% DmgSlashSmall64.png Slash and 43.75% DmgViralSmall64.png Viral.
    • Explosion has innate DmgViralSmall64.png Viral damage – effective against Flesh and Cloned Flesh.
    • Explosion delay reduces likelihood of inflicting self-stagger.
    • Initial hit and explosion apply status separately.
    • Explosion does not need direct line of sight to deal damage and will penetrate walls.
  • Mod TT 20px.png Heavy Caliber's accuracy penalty is minimal on this weapon.
  • Silent.
  • On kill, bodies will follow the arrow that killed them, damaging enemies in their path and pinning the corpse to walls.
  • Can benefit from Mod TT 20px.png Firestorm (Mod TT 20px.png Primed) and Mod TT 20px.png Cautious Shot.
  • Fire rate mods apply double their bonuses.
  • Innate two Naramon Pol.svg polarities.

  • Each tick and the final explosion can damage and proc status independently.
  • Tendrils do not require line of sight to latch onto enemies, but cannot pull enemies through walls.
  • Will not pull or damage enemies inside a Nullifier bubble. Will deal damage to the bubble on the arrow hit and on explosion, but not on pre-explosion damage ticks. This is the case whether firing outside the bubble or from within the bubble.
  • Mod TT 20px.png Thunderbolt causes the arrow to explode immediately after landing.
  • Mod TT 20px.png Firestorm only affects the radius of the final blast, and does not increase the range of appendages.


  • Because of the weapon's appendages pulling enemies into a cluster, it synergizes extremely well with Warframe ability augment mods that require enemies within the said abilities' area-of-effect to trigger, such as Mod TT 20px.png Spectrosiphon and Mod TT 20px.png Pilfering Swarm.
  • Good primary weapon choice for Specters, because of its crowd control abilities and high base damage.
  • Can be used to pull enemies into XakuIcon272.png Xaku's Gaze to ensure their armor is reduced (or removed) before the explosion takes place.


  • A Proboscis is the elongated, tube-like mouthpart on insects like butterflies, mosquitoes, etc.
