Figured I'd do something a little challenging today, so picked FL25 +1 tower (Mimiron's - Tower of Flame).
Used 2 bikes, 5 demos full of Pyrite and a siege to finish (Wanted 3-car garage )
I didn't shoot a video, because the pyrite casts were taking long enough to go off as-was. I did screenshot just after I finished though

I was raid-grouped with a lvl10 on a trial account (Handy, those things). Average ilvl of 371.
It struck me after completing that this may even be a world-first, however unimpressive it seems when compared to soloing the Lich King.
