I've had it like once and it's the only reason my Salt Mine score is sat where it is right now. Kinda freaked out a little because it was on my Titan where I was testing out a new Solar build with the bonk hammer exotic and I just dumped my entire super and a fully fuelled Dragon's Breath rocket on it in an effort to make sure he didn't escape and then somehow still finished with nearly two minutes spare? Only time I had it, not had it since. Pretty much the only reason I decided to push myself for the helmet and work with some guardians with the most terrible modifiers ever on Pricing Grounds to get that score up. Now I'm sat pretty over 100 points.
