I hopped on today to do some daily crucibles, just to earn some passage coins. A couple of clan mates were on running weeklies, but I have finished those already. Nightfalls were done, as well as most of the prison runs I planned on doing.
A personal friend of mine, new to Destiny, joined my fireteam to see what I was working on. I wasn't doing anything productive so I asked him if he completed the weekly or the Nightfall yet. He is only a 32, and informed me that he was unable to find anyone to run the Nightfall with. He tried to solo it, but doesn't have the weapons or experience to do it yet.
I didn't give him a choice and took him to the Nightfall. We were both running Sunsinger Warlocks. I pulled out my big guns for this Solar burn Cabal week. Ascended VoC, Icebreaker, and Hunger of Crota. We work our way to the end and melt Valus.
And then it happens...
Those beautiful yellow letters popped up in the bottom left of the screen. "Squirms found Gjallarhorn." I did the yelling for him, as he hasn't played long enough to know what just happened. His current exotics are No Land Beyond, Dragons Breath, 4th Horseman... and now this. I spent the next few minutes explaining to him about Tracking, Proximity detonation, and of course, Wolfpack Rounds.
tl:dr, Took a new guardian through the Nightfall to earn him his first Gjallarhorn.
