Expel Infested

Faction-damage pistol mod

Released Jul 13, 2013

Expel Infested increases a pistol’s damage against Infested, reaching 1.3× at rank 5. Consider it when you can spare a standard pistol slot for encounters against that faction.

Understand Expel Infested

Useful when…

  • Faction-specific pistol setups against Infested

Effect and compatibility

This standard, Madurai-polarity pistol mod raises damage against Infested from 1.05× at rank 0 to 1.3× at rank 5. It fits pistols; it does not provide that bonus against other factions.

Ranking and slot tradeoff

It has five ranks and a base drain of 4. The example fusion costs rise from 20 Endo and 966 Credits for ranks 0→1 to 320 Endo and 15,456 Credits for ranks 4→5. Rank it when the faction bonus justifies the escalating investment and standard slot; the listed bonus is not a final damage total. Flawed Expel Infested is a lower-capacity alternative, while Primed Expel Infested reaches a higher faction multiplier; neither changes this mod’s faction-specific role.

Practical limit

This mod is incompatible with Flawed Expel Infested and Primed Expel Infested. Do not treat it as a general-purpose damage bonus when fighting other factions.

Limitations and tradeoffs

  • Uses a standard pistol slot for a faction-specific effect.
  • Higher ranks require progressively larger fusion costs.

Common mistakes to avoid

  • Expecting the faction bonus to apply against non-Infested enemies.
  • Equipping an incompatible Flawed or Primed version alongside it.
