Mimiron's Head drops from Yogg-Saron in 25-player Heroic Ulduar, and only when the raid kills him with 0 Keepers assisting — the hard mode achievement Alone in the Darkness. The drop chance is roughly 1% per kill, and Ulduar sits on a weekly lockout, so that is one attempt every 7 days per character. Priced per attempt, from $5.39 a run cycle.
This is a skilled service, not a plain farm. Leaving all four Keepers — Freya, Hodir, Mimiron and Thorim — inactive strips the raid of every buff the encounter was built around, drops the Sanity ceiling and turns Yogg-Saron into the hardest fight of the tier. Very few guilds ever cleared it on level. Any seller quoting you "Mimiron's Head runs" without saying 0 Keepers is quoting a normal Yogg-Saron kill, and a normal kill cannot drop the mount at all.
How many weeks it realistically takes. At about a 1% chance per 0-Keeper kill, half of all farms need roughly 69 attempts and about a quarter finish inside 28. On a single character at one lockout a week that is years, which is why the blocks scale: 5 cycles $26.95, 10 cycles $53.90, 25 cycles $134.75, and why running the kill across several of your characters in the same week is the only honest way to compress it. Extra characters multiply lockouts; they never raise the 1%.
The mount is account-wide. Mimiron's Head is Bind on Pickup, so the kill has to happen on your own character, but once it is looted the mount lands in your account-wide collection and every character you own can ride it. There is no mailing it, no trading it and no delivery version of this service.
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 adds 20% and Super Express 40% for queue priority. US realms are the default, EU is on the region switch above. Manual play, no bots, PC only.
