  • This mod is purely a cosmetic and does not affect damage or status effects in any way.
    • Although purely cosmetic, it technically affects the hitbox size as well, which sometimes may land headshots easier, or harder because of the head hitbox being blocked by another hitbox of an enemy body part.
  • The effect also works on other Warframes if the player has been affected by a Radiation b 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 (Kuva) GrineerMicrowaveGun Nukor.
