Understand Polar Magazine
Useful when…
- Add Cold damage to a compatible Archgun in a standard slot.
- Use it instead of a different named effect when Cold is the desired elemental addition.
Effect and compatibility
Polar Magazine grants +20% Cold at rank 0, +80% at rank 3, and +120% at rank 5. It is an Uncommon Archgun mod with Vazarin polarity, a standard slot, base drain 4, and maximum rank 5. It is explicitly incompatible with Primed Polar Magazine.
Rank investment
The listed rank 2-to-3 step costs 80 Endo and 3,864 Credits to reach +80%; the final step from rank 4 to 5 costs 320 Endo and 15,456 Credits to reach +120%. Consider an intermediate rank when the extra Cold bonus does not justify that last listed investment or added drain.
Compare the named alternatives
Primed Polar Magazine lists +187% Cold and the same polarity and base drain, but has a maximum rank of 10 and is incompatible with this mod. Ammo Chain increases maximum ammo by +100%, while Archgun Ace grants fire/charge rate and reload speed after a headshot kill for 9 seconds. Those are ammo capacity and conditional handling effects, rather than Cold damage.
Acquisition
Listed sources include Earth/Erpo, Europa/Gamygyn, and Neptune/Salacia Mobile Defense, plus several enemy drops. Each location has its own listed chance; the supplied source data does not give one universal chance.
Limitations and tradeoffs
- Consumes a standard Archgun slot for Cold damage.
- Cannot be equipped with Primed Polar Magazine.
Common mistakes to avoid
- Do not equip it alongside the explicitly incompatible Primed Polar Magazine.
- Do not confuse Cold damage with increased maximum ammo or a conditional reload benefit.
