Barrow Deeps raid guide
Barrow Deeps' planned size, unlock, Legacy boss challenge, and the unresolved raid-count question.
The raid calendar gives you a place to start, then the roster questions show up. Barrow Deeps has a planned size, a scheduled unlock, and a Legacy boss objective on the record. Blizzard's raid count is harder to read: its announcement says two new raids, while a roadmap card has three entries. Here, those plans and the unresolved count stay clearly labeled.
Quick answer
Blizzard plans Barrow Deeps as a maximum-level 10-player raid, with the raid unlock scheduled for December 9, 2026.

What the schedule establishes
The September 12 What's Next Panel Recap sets the planned size and unlock window, but gives no entry route or encounter instructions. It pairs the raids with new tier sets and a legendary reward still to be revealed; it does not say which raid provides which reward.
For the wider schedule, see the raid overview; the Legacy guide explains the account-wide challenge context.
What the Legacy challenge adds
Blizzard's September 23 Legacy System article adds one objective: defeat all 8 Barrow Deeps bosses. It establishes a planned total, not a named roster. The article does not state boss order or provide encounter mechanics, a map, loot, or a walkthrough.
Why the raid count is unresolved
The Opening Ceremony recap says Blizzard is adding two new raids. The September roadmap card lists three raid entries, including Onyxia's Lair. The sources do not say whether Onyxia is new to Forever or an existing raid returning on the schedule. Keep both statements visible: the card does not establish three new raids.
