I've recently got the Netwatch Netdriver Mk 5, which among other things allows to spread offensive QHs to targets within 6 meters (sweeeet Jesus is that nice). Now whenever I use the Contagion QH it keeps spreading to enemies that are already doing their incapacitated animation, resulting in them slowly but surely forming a nice, thick pool of blood and stop moving and breathing shortly thereafter. That looks quite lethal if you ask me.
