Lol. I wear ahamkara spines on my hunter for the extra trip mine and longer duration in Mayhem. You can literally place a trip mine like every 10 seconds or something stupid like that. And the amount of time they stay active is freaking hilarious. I have placed one, died, went around and killed shit without throwing any nades and got a kill from the one I placed before dying. Pair that with double throwing knives for an extra good time.
