Riddler's Mind-Worm is the secret serpent mount Blizzard buried in patch 7.2 and left for the Secret Finding Discord to crack in April 2017. Nothing drops it. It is claimed by reading 8 hidden pages in strict order, then looting the Gift of the Mind-Seekers chest on the Westfall coast at 30.5, 28. Blizzard later confirmed the page numbers 9, 78, 161, 655, 845, 1127, 2351 and 5555 spell the ISBN of Warcraft Chronicle Volume 1, and that each clue was drawn from an illustration inside that book.
Where the pages sit: the Legerdemain Lounge bookshelf in Dalaran, the Twilight Grove moonwell in Duskwood at 49, 33, the Ragnaros platform inside Firelands, the coast east of the Lost City of the Tol'vir in Cataclysm-phase Uldum at 70, 78, the Sha of Pride room in Siege of Orgrimmar, the Well of Eternity dungeon in the Caverns of Time, the tiger statues below the Shado-Pan Monastery in Kun-Lai Summit at 34.6, 50.9, and the Steps of Fate statues back in Uldum at 76.4, 53.6.
The gates are order and phasing, not luck. A page only appears once the page before it has been read, and Uldum has to be flipped to its Cataclysm version by Zidormi in Ramkahen or two pages stay invisible. Two more sit behind bosses: all 7 Firelands bosses have to fall before the Ragnaros platform opens, and Siege of Orgrimmar has to be pushed to its 4th boss. Community guides split on whether page progress survives the weekly reset, with several reporting it wipes on maintenance, so the route is always planned to finish inside one reset week rather than banked half-done.
Realistic total: roughly 2 to 4 hours, most of it the two legacy raid clears and cross-continent riding. Both raids are soloed at max level, so no group and no lockout partner is needed. The 2-hour block covers a clean run on an account with flying and the 4-hour block covers starting Firelands and Siege of Orgrimmar cold. If a reset forces a rerun, the extra time is booked as repeat blocks at the same hourly rate: 2 hours for $26.99, 4 for $53.99, 6 for $80.99, or 10 for $134.99. There is no loot roll anywhere in this chain, so the chest is guaranteed the moment the eighth page is read.
Delivery: the mount is account-wide once learned, rides at level 10 and flies at Expert Riding. US is the default region and carries its own ladder, with a separate EU ladder next to it. Piloted play is standard, Self-play Remote adds 30%, Express adds 20%, and Super Express adds 40%. Manual PC play only, scheduled in ET or PT for US players.
