Primed Firestorm

Rifle radial-attack blast-range mod

Released Dec 1, 2020

Primed Firestorm increases blast range for rifles with radial attacks. Consider it when expanding the affected area of a compatible weapon matters enough to spend a standard mod slot.

Primed Firestorm GUIDE

Understand Primed Firestorm

Useful when…

  • Increasing blast range on a rifle that has radial attacks.
  • Choosing between the higher-rank Primed version and the lower-rank Firestorm according to capacity and investment.

Effect and compatibility

The mod improves blast range on weapons with radial attacks. Its listed bonus is +4% at rank 0, +24% at rank 5, and +44% at rank 10. It is a standard rifle mod with Madurai polarity, base drain 6, and maximum rank 10. The bonus describes range, not damage.

Investment and slot choice

Each rank increases the listed blast-range bonus, while high-rank fusion steps are costly: the examples include 1,280 Endo and 61,824 Credits from rank 5 to 6, and 20,480 Endo and 989,184 Credits from rank 9 to 10. Check whether the range increase is useful on your radial-attack rifle before investing in the final ranks. It occupies a standard slot rather than a rifle Exilus slot.

Alternatives and limitations

Firestorm is the matching standard mod, listed with maximum rank 3; Primed Firestorm explicitly excludes it, so they are alternatives rather than compatible additions. Aerial Ace is a rifle Exilus mod that refreshes double jumps on kills while airborne, and Agile Aim is a Conclave Exilus mod that improves movement speed while aiming. Neither provides blast range, so they are not direct replacements.

Limitations and tradeoffs

  • Its benefit applies to weapons with radial attacks; it does not add damage.
  • High fusion ranks have substantial Endo and Credit costs, and it uses a standard mod slot.

Common mistakes to avoid

  • Assuming it increases damage rather than blast range.
  • Using it on a rifle without radial attacks.
  • Trying to equip it together with Firestorm.
