Curated and corroborated — the export and the wiki independently state the same effect. None of this mod's effect is counted in a build's stats.
- Outside the engine: +90% Ammo Maximum
Drain by rank
- R0 2
- R1 3
- R2 4
- R3 5
- R4 6
- R5 7
A matching polarity halves the drain, rounded up; a mismatched one costs more than no polarity at all.
