Exactly what the title says. Found it a while ago when I was messing around with a friend. Since I didn't find anybody complaining about it, I thought it was a good idea to report this. It will only work if you're close to the person, so you can't just snipe people with the grenade. Hug someone and throw the grenade at the person (Or on the ground, as long as it hits both you and the poor target). It only works when using the exotic gauntlets Ashen Wake.
