So I was messing around with this spec for resetting Rift energy (one of the bonuses for Starfire) by killing enemies with Fusion Grenades. Normally, you get your Rift energy fully restored when you kill with a Fusion Grenade, however, if your feet are not firmly planted on the ground when you toss the grenade, you get no energy at all. Conflict between "Heat Rises" and "Fusion Harness"? Or maybe "Winged Sun" and "Fusion Harness" I guess.
