Understand Cryo Rounds
Useful when…
- Add Cold damage to a rifle using a standard rifle mod slot.
Effect and fitting
Cryo Rounds provides +15% Cold at rank 0, +60% at rank 3, and +90% at rank 5. It is a standard Vazarin-polarity rifle mod with base drain 6. The listed incompatibilities are Flawed Cryo Rounds and Primed Cryo Rounds, so these variants cannot be equipped together.
Rank investment
The listed cost rises sharply with rank: rank 0 to 1 costs 20 Endo and 966 Credits, rank 2 to 3 costs 80 Endo and 3,864 Credits, and rank 4 to 5 costs 320 Endo and 15,456 Credits. Each rank increases the Cold bonus, so stop at a rank that fits the build's capacity and investment priorities.
Variants and distinct functions
Flawed Cryo Rounds reaches +40% Cold with base drain 2 and maximum rank 3; it trades bonus strength for lower base drain. Primed Cryo Rounds reaches +165% Cold, with maximum rank 10 and base drain 6. Both are listed as incompatible with this mod. Aerial Ace occupies an Exilus slot and refreshes double jumps on kills while airborne, so it addresses movement rather than Cold damage.
Limitations and tradeoffs
- Uses base drain 6 for a maximum +90% Cold bonus.
- Cannot be equipped together with the Flawed or Primed variant.
Common mistakes to avoid
- Attempting to equip another Cryo Rounds variant at the same time.
- Assuming Aerial Ace supplies Cold damage because it is also a rifle mod.
