Invincible's Reins drop from the Lich King, the final boss of 25-player Heroic Icecrown Citadel, at roughly a 1% chance per kill. Icecrown Citadel is on a weekly, per-character lockout, so one character produces exactly one attempt every seven days. Attempts start at $5.39 per run cycle.
This is a multi-week farm and we will not sell it as a one-run carry. At about 1% a kill the median farm lands near 69 weekly attempts — half of all farms finish sooner, plenty run longer, and a lucky few end on the first Lich King kill. Blocks exist because of that math: 10 cycles for $53.90 is roughly a 10% shot, 25 cycles for $134.75 is roughly 22%, and 5 cycles cost $26.95.
Alts are the only honest accelerator. Every eligible character carries its own Icecrown Citadel lockout, so ten characters consume ten cycles in one week instead of one. More characters buy you more attempts per week; they do not raise the 1% chance on any single kill, and anyone claiming otherwise is selling arithmetic that does not exist.
The mount is account-wide once it is learned. Invincible's Reins are Bind on Pickup, so the kill has to happen on a character you own, but the moment the reins are used the undead frost wyrm sits in your account's mount collection on every character and every realm.
How it is delivered: piloted by default, since the lockout and the loot both belong to your character, or Self-play Remote for 30% more with the account staying on your machine. Express and Super Express move you up the queue. US realms are the default and EU is on the region switch above. Manual play, no bots, PC only.
