  • This mod is cosmetic and does not affect damage or apply a status effect.
    • Although mostly cosmetic, it technically affects the hitbox size as well, which may sometimes make landing headshots easier or harder because of the head or body part hitbox of an enemy becoming blocked.
  • The effect also works on other Warframes if the player has been affected by a DmgRadiationSmall64.png Radiation proc.
  • The effect is only applied on non-critical hits.
  • As with Riven Mods, only one Peculiar mod can be equipped on a Warframe at a time.


  • This mod was first showcased on Devstream 110.
  • This mod allows all ranged weapons to achieve a similar growth mechanic innately available to the KuvaNukor.png (Kuva) GrineerMicrowaveGun.png Nukor.
