Max drain 14 unmatched / 7 on a matching Madurai polarity. Forma the V early — this is a forever slot on most rifles.
Farm call: Farm early-planet Spy Rotation C (Hapke, Cambria, Arval, Suisei) at 8.6% — reliable and low-friction.
Same damage-slot conversation — pick the peer when the condition fits.
