Understand Primed Cleanse Grineer
Useful when…
- Build faction-specific shotgun damage for Grineer enemies.
- Keep it at a partial rank when capacity or fusion resources are more useful elsewhere.
Effect and restrictions
The listed Grineer multipliers are 1.05× at rank 0, 1.3× at rank 5, and 1.55× at rank 10. It is a standard-slot shotgun mod with Madurai polarity and base drain 4. It cannot be equipped with Cleanse Grineer or Flawed Cleanse Grineer.
Rank tradeoff
Cleanse Grineer reaches 1.3× at rank 5 and the Flawed variant 1.12× at rank 3. The Primed version reaches 1.55× at rank 10, with its final rank step costing 20,480 Endo and 989,184 Credits. Consider whether the additional listed multiplier is useful for your Grineer missions before committing the final-rank resources.
Slot choice
It uses a standard shotgun slot and targets Grineer specifically. Accelerated Blast offers a different listed combination of +60% fire rate and +60% Puncture; it does not provide the same faction multiplier.
Limitations and tradeoffs
- The effect is matchup-specific and consumes a standard mod slot.
- Max rank's final step requires substantial fusion resources.
Common mistakes to avoid
- Using it as if its multiplier affected every faction.
- Pairing it with Cleanse Grineer or its Flawed version.
