While I was out in the Vanguard Heroic Strike playlist, dabbling in my admittedly underused hunter (Which will now not be staying so dusty for long) I was running Bladedancer, an unusual choice, since my preferrence is Gunslinger. I like being able to be a Gunslinger with Kephri for multirole Damage and Medic. So, Bladedancer. I have my skill lines about halfway unlocked so I'm running Showstopper, Higher jump, Flux grenades, Backstab, Encore, Path Forbidden and Way of the Fearless, and have on my best gear. Kephri is doing it's thing, so I pop Arc Blade, crouch, invisibility goes up and I rush out into the middle of a huge group of enemies. I hit Showstopper and had to stop for a second as my entire mind and perception had just witnessed greatness. Everything. EVERYTHING. ALL OF THEM. They had ALL taken both the backstab damage, AND the Kephri venom, and I was now standing in the middle of the most wonderful field of shimmering emerald light as they quickly ticked away in a Thornlike poison. Of course I couldn't stand around to think about good old days in the crucible getting spikes bigger than my head put through my torso, but it was something grand. SO I experimented. If you're invisible, you can poison with your Arc Blade with Showstopper, or your basic strikes after each use of Vanish, but for some reason not Razor's Edge. Probably because of how slow it is and how far it goes, and you uncloak instantly when you use it. That's all. Just had to share a neat little trick for clearing entire rooms in pvp and pve that I found, and a cool story.
