I finally got the rarest tonic in Guild Wars 2. The Endless Fractal Tonic. That damn thing has such horrible RNG that I feel like I should go buy a lotto ticket right now. Its rarity is easily the same as having a precursor drop and after a year of trying to get it I gave up for 6 months. Then over the past month I started playing fractals again, finished my legendary back piece and then got this tonic.. I felt like I had a heart attack when I saw it in my inventory. I'll make a video of it later this week.
