Overcome with Infestation, this bow's arrows now spread poisonous contagion to any surface they hit.

The Mutalist Cernos is an Infestation w Infested Cernos Cernos, possessing a lower critical chance in exchange for a significant increase in status chance. The bow also releases DmgToxinSmall64 Toxin spores that follow arrow impacts, producing lingering damage clouds.

This weapon can be sold for Credits64 8,500. It is also a requisite ingredient for ProboscisCernos Proboscis Cernos.

Characteristics[]

  • This weapon deals primarily DmgImpactSmall64 Impact damage. Spore clouds have innate DmgToxinSmall64 Toxin damage

    • Spore cloud does not inflict self-stagger.
    • Initial hit and spore cloud apply status separately.
    • Spore clouds will alert enemies, despite the weapon being silent.
    • Spore clouds appear as a second projectile 0.25 second after the arrow impact, slightly delaying its presence.
    • Spore clouds will follow arrow impacts even on ragdolled corpses.
    • Can benefit from Mod TT 20px Firestorm (Mod TT 20px Primed).

Notes[]

  • In regards to Riven Mods, the Mutalist Cernos is considered separate from the rest of the Cernos Cernos family and cannot use Cernos Rivens; they must be specifically for the Mutalist Cernos.
  • Upon hitting an enemy or an object, the Mutalist Cernos's spore will create a small DmgToxinSmall64 Toxin cloud that deals damage every second to any enemy within its radius. This cloud lasts for 10 seconds.
    • The spore cloud deals 5 DmgToxinSmall64 Toxin damage per second modified by any base damage and elemental damage mods installed on the weapon.
    • The cloud's primary damage is of the same damage type(s) as the elements installed on the weapon, with the innate DmgToxinSmall64 Toxin damage combining with them last, similarly to other pure elemental weapons.
    • Each tick from the cloud has a chance to proc DmgToxinSmall64 Toxin as well as any modded elemental status effect, with each stack displayed separately to the cloud's larger primary damage ticks.
    • The forced DmgToxinSmall64 Toxin proc damage over time is calculated as normal; 50% of the spore's base damage adjusted by base damage mods, plus the DmgToxinSmall64 Toxin damage bonus from mods. Unmodified this is 2.5 DmgToxinSmall64 Toxin damage per second stacks (displayed rounded down) in addition to the cloud's primary damage ticks. Since DmgToxinSmall64 Toxin procs last 8 seconds, and the proc is refreshed every second of the 10 second cloud duration, the DmgToxinSmall64 Toxin proc duration will last a maximum of 18 seconds from the initial spore cloud damage tick.
    • The cloud itself is not affected by status duration mods like Mod TT 20px Continuous Misery, but the cloud's procs of DmgToxinSmall64 Toxin, DmgFireSmall64 Heat or DmgGasSmall64 Gas of course are.
  • While the cloud effect is similar to the Torid Torid, the clouds are smaller and can sometimes spread between enemies.
  • The user interface will not display elemental damage mods after combining with the toxin due to the calculation only displaying base damage initially and modded arrow damage (effectively treating the cloud as if it were the modded damage, thus reducing arrow elements from the UI), resulting in elemental damage displayed after first to be inaccurate.
  • The number of spore clouds are affected by Multishot.
  • For charged shots, the spore's critical chance and critical multiplier will be boosted, keep the same as the arrow's values. However, the spore's base damage is unaffected by charging.
  • Altering the Projectile Speed will affect both the arrow and the spore, including Mod TT 20px Terminal Velocity, Mod TT 20px Jet Stream and possible Riven Mods' stats.

Known Bugs[]

  • Mod TT 20px Galvanized Aptitude is multiplicative to base damage sources on direct hits from uncharged shot and its cloud.
    • The cloud from uncharged shot benefits from the multiplicative effect only on the attached target.

Tips[]

  • The Mutalist Cernos is ill suited for stealth missions, as enemies that are damaged by lingering toxin clouds will be immediately alerted to the Tenno's presence.
  • Multiple spore clouds can be a hindrance as they may obscure the player's vision.
  • The continuous damage dealt by spore clouds is quite effective at in taking down Nullifier and Arctic Eximus shields faster compared to other bows, on top of dealing direct damage to the shielded enemy's health.
  • Any arrow that procs Mod TT 20px Thunderbolt's explosion will not result in a spore being fired, making its usage ill-advised.
    • Likewise, arrows landed on an ally or any containers (including resource deposits) will not have a spore followed, a significant difference from Torid Torid.
  • Mods that add sufficient punch through will often result in the spore landing well behind a targeted enemy. While this may allow the Mutalist Cernos to deal with cameras, turrets, and other stationary destructibles or objects from behind obstructions, it is suggested that such mods be avoided, as the downsides far outweigh the benefits.
  • Unlike the Torid Torid's projectile, the spores will attach to a Nullifier bubble (or Arctic Eximus Globe) at the point of impact, continuously applying damage and shrinking the bubble. This makes the bow an efficient means of combating Nullifiers in Bow-only Corpus Sorties.
  • Can utilize Mod TT 20px Split Flights effectively, as damage from the clouds will refresh the duration of the multishot bonus, and cause the weapon to fire a large spread of arrows for excessive amounts of procs.

Bugs[]

  • Mutalist cloud from the second arrow may have a base status chance of around 15~23% or is not affected by status chance mods like the Ferrox Ferrox lightning rings.
  • Similar to a bug previously present on the Torid Torid, the clouds that stick to enemies after getting shot with an arrow will sometimes do no damage to that enemy.
  • Relevant cloud spores toxic dmg/procs noncovalent

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.
