Understand Primed Expel Grineer
Useful when…
- Focusing a pistol build on damage to Grineer.
- Choosing the stronger faction multiplier over regular or flawed Expel Grineer.
Effect and target
The mod’s faction-specific multiplier against Grineer is x1.05 at rank 0, x1.3 at rank 5, and x1.55 at rank 10. Its listed effect is tied to Grineer targets; it is not a general pistol damage bonus.
Compatibility and alternatives
It uses a standard pistol slot, has Madurai polarity and base drain 4, and excludes Expel Grineer and Flawed Expel Grineer. Regular Expel Grineer reaches x1.3 at rank 5; Flawed Expel Grineer lists x1.1 at rank 3. Accelerated Isotope is a separate standard-slot mod with +60% Radiation and +40% Fire Rate, offering different effects rather than the same Grineer multiplier.
Rank costs
It can be fused through rank 10. Rank 5 provides x1.3 against Grineer; raising it from rank 9 to 10 costs 20,480 Endo and 989,184 Credits for the maximum x1.55 multiplier. Invest further when the target-specific increase matters to the intended setup.
Limitations and tradeoffs
- The damage multiplier applies to Grineer targets specifically.
- The final rank costs 20,480 Endo and 989,184 Credits from rank 9.
Common mistakes to avoid
- Assuming the x1.55 multiplier applies to enemies other than Grineer.
- Pairing it with Expel Grineer or Flawed Expel Grineer, which are explicitly excluded.
