Reins of the Onyxian Drake drops from Onyxia, the only boss of Onyxia's Lair, and specifically from the level 80 Cataclysm-era version of the raid rather than the original level 60 one. The drop chance is roughly 1% per kill and the raid sits on a weekly lockout, so each character gets one real attempt every seven days. Run cycles start at $5.39.
How many attempts it honestly takes. At about 1% a kill there is no pity timer and no guaranteed run count: 5 cycles is roughly a 5% cumulative chance, 10 cycles about 10%, and the 25-cycle block about 22%. Community loot samples put the real rate near 1.45%, which nudges those odds up but does not change the shape. That is why this is sold by the attempt, in blocks of 5 for $26.95, 10 for $53.90 and 25 for $134.75.
This is the cheapest legacy mount farm we run, on purpose. Onyxia at level 80 is trivial for a modern max-level booster — a few minutes solo, no group, no attunement, no key chain — so a single attempt costs $5.39 instead of the hundreds a Kael'thas or Lich King farm costs. Low delivery cost is exactly what makes a 1% mount worth grinding.
The drake is account-wide. Retail mounts go into the Mount Journal for the whole account, so once Onyxia finally drops it, every character you own can ride it. The mount is Bind on Pickup, so the kill has to land on your own character — one attempt per character per week, and extra characters are the only honest way to stack more cycles into a single reset.
How it is delivered: piloted by default, or Self-play Remote for 30% more if you want the account to stay on your own machine. Express and Super Express move you up the queue. US realms are the default; EU is on the region switch above. Manual play, no bots, PC only.
