Look it up on WowheadHow to get it
Rare drop from Lady Jaina Proudmoore, the ninth and last boss of Battle of Dazar'alor, on Mythic difficulty only; it is in the Proudmoore Strongbox she leaves. Each faction has its own entrance. An account that has killed her on Mythic once can skip straight to her by talking to the NPC at the start of the raid.
Chance 0.66% once a week, so about 152 tries on average — Wowhead: 305 mounts in 46,130 recorded loots of the Proudmoore Strongbox, the chest Jaina leaves (item page read 2026-10-10; the tooltip shows no chance and Jaina herself carries no count). The chest's count is not split by difficulty although the mount is Mythic-only, and it reaches back to before patch 9.0.2 (November 2020), when the drop was certain, so it is not a clean figure for today. Players quote about 1%, which Blizzard never published; the wiki says only 'very rarely'. Wowhead's client data for 1-16 July 2025, during Collector's Bounty with its announced +5%, showed 4.66% (margin 0.49%) on Mythic

Getting there
/way Tiragarde Sound 74.4 28.3 - Take the portal from Wizard's Sanctum to Boralus*
- Fly the rest of the way
/way Zuldazar 54.3 30 - Take the portal from Pathfinder's Den to Zuldazar*
- Fly the rest of the way
/way is for the TomTom addon. Travel times are estimates: flying at 55 yards a second in a straight
line and 30 seconds for a portal. A star marks a portal that needs a quest or other unlock done first.
Notes and sources
One try a week per character. The 45 minutes are an estimate for the first visit, a clear of all nine bosses on Mythic; with the skip a visit is about 10 minutes.
The skip was added in June 2020 (Wowhead comments of 2020, 2024 and 2025): once Jaina has died on Mythic, the NPC at the start of the raid takes the group straight to her. It is account-wide, so other characters can use it without having been inside before, and one player who has it can bring a whole group. Using it shuts the other bosses for that lockout, even if Jaina is not killed (comments of 2023 and 2024), so whoever also wants G.M.O.D. from High Tinker Mekkatorque kills him first.
Players' advice for the fight (2024): no Bloodlust or Heroism, or Jaina puts up an ice block. If she dies before the sea freezes, the strongbox can appear out on the water, and the loot then comes by mail (comments of 2024 and 2025).
About 150 kills are expected at 0.66% and 100 at 1%. Reported kill counts since 2024 run from 1 and 3 to 33, 78, 115, about 130 and about 200. History (wiki): one mount per Mythic kill at first, two from a hotfix of 14 February 2020, and the chance 'greatly reduced' in patch 9.0.2.
Both entrances are from the game's own table; the wiki gives the same doors as 70.5, 35.3 in Boralus Harbor and 38.8, 2.4 in Dazar'alor and lists no condition for entering. Alliance and Horde meet the second and third bosses the other way round (wiki); Jaina is last for both. No guide is linked: it is one boss.
Confidence in this entry: medium. Looked up in 2026.
