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

Acquisition[]
The Proboscis Cernos's blueprint can be purchased from the Market.
Notes[]
- 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.
- Thunderbolt causes the arrow to explode immediately after landing.
- Firestorm only affects the radius of the final blast, and does not increase the range of appendages.
- Direct hits on enemies will immobilize them during the tendril pull as they panic, including enemies with Overguard.
Tips[]
- 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 with
Gara's Spectrosiphon and 
Hydroid's 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
Xaku's Gaze to ensure their armor is reduced (or removed) before the explosion takes place.
Trivia[]
- A Proboscis is the elongated, tube-like mouthpart on insects like butterflies, mosquitoes, etc.

- Fixed certain bosses being permanently stun locked by the Proboscis Cernos stun effect.
Update 32.0 (2022-09-07)
- Ammo Changes
We understand the power fantasy of these weapons is very popular for some, so our first approach was to keep them powerful, but limit how often they can be used by making changes to ammo pick-up.
Ammo Pickup Overrides
The following weapons now have ammo pickup overrides, meaning they gain less from picking up ammo. This mostly applies to AoE weapons, in hopes that players will become more deliberate with their aim to make the most of their Ammo pools. The following lists the specific ammo pick up overrides per weapon category.
Primary Weapon Ammo Pick Up Overrides
1 Ammo per Pick Up:
Many weapons have also had their maximum ammo capacity adjusted.
Primary Weapons:
- Proboscis Cernos: From 9 to 7
- Headshot Damage Changes
During playtesting, the ammo changes alone weren’t enough to significantly change things for AoE weapons. So instead of tightening these values to be overly restrictive, we chose to address other factors that make these weapons so strong, such as headshot damage.
Our approach here is two-fold, to reduce the impact of headshots for AOE weapons, but to also make precision headshots pack a larger punch overall.
- Radial damage no longer gains extra headshot damage or triggers headshot conditions.
- This is primarily targeted at the Ignis Wraith - as a “flamethrower” weapon, it’s hard to imagine a blanket of elements being precise enough to target weak points specifically. Explosive projectiles themselves can still land headshots, so there is still a reason to aim with most weapons for maximum damage.
