There aren't any, too my knowledge, here's my idea. Gemini Trio - SMG - Kinetic - Exotic 900RPM, 35 round mag Intrinsic: One way or another, bonus mobility on precision kills & bonus resilience on non-precision kills, further kills extend timer(s) but do increase effect. Corckscrew rifling, Tactical Mag, Short action Stock Trait: A third option: multi kills grant bonus recovery further kills extend timer but do increase effect.
