Here’s the story of two (un)lucky players who looted Reins of the Heavenly Onyx Cloud Serpent, a mount with an extremely low drop chance on the Dragonflight Beta, on the very same day.
The first report comes from Bodehn who looted the mount from the Sha of Anger on their Evoker.
The second person who received the mount on the same day was Jibbles2020.
With an abysmal drop chance, both tried to figure out if there was something wrong with the drop rate on the Beta and had others test it out. Unfortunately, nobody else got the drop.
Moral of the story: Never farm something on PTR/Beta you still don’t have on live servers!
