12-month subscription promotion.

Notes:

This celestial bovine is part of a limited-time 12-month subscription promotion in 2025. Players who sign up to a 12-month subscription, or are already on an existing 12-month recurring subscription with a future renewal date, will receive this mount and a bunch of other rewards, including the Astral Aurochs, the Herald of Sa'bak (also available with 6-month subs), and the upcoming 2026 Lunar New Year 6-month Subscription bonuses (to be officially revealed, but they are horse-related). See Blizzard's news article for more details.

Note that this information was valid at the time of writing (October 2025) but may change without notice and you should check Blizzard's official pages carefully before signing up to a subscription. Once the promotion period has ended it is likely - though not guaranteed - that this mount will become available as a standalone product in the Battle.net shop.
