Battle for Azeroth Keystone Master: Season One required timing all ten BfA dungeons at Mythic +15 or higher during Season 1 (September 2018 to late January 2019, Infested seasonal affix). It is a Feat of Strength now and can no longer be earned. There was no mount attached to it; seasonal Keystone Master mounts only started in Shadowlands, so the BfA version was purely an achievement for the record.
BfA Keystone Master: Season One at a glance
| Requirement | Every Season 1 dungeon completed at +15 or higher, inside the timer |

| Seasonal affix | Infested (extra add mechanics on affected mobs) |
| Season window | Early September 2018 to late January 2019 |
| Reward | The achievement itself — no mount, no seasonal cosmetic |
| Status today | Feat of Strength, unobtainable |
- Depleted runs did not count. Each dungeon needed a timed clear at +15 or above; over-time completions gave loot but no credit.
- Only the level mattered, not the affix combination. A +15 Tyrannical and a +15 Fortified week both qualified.
- Kings' Rest and Siege of Boralus were faction-tied for the story, but both factions could run them in Mythic+ through a keystone, so both were needed for the achievement regardless of faction.
- A companion achievement, Battle for Azeroth Keystone Conqueror: Season One, used the same list at +10 or higher.
What was BfA Keystone Master Season 2?
Season 2 opened with patch 8.1 content in late January 2019 and swapped Infested for Reaping, the affix that sent waves of slain enemies' spirits back at you at fixed enemy-forces percentages. The Keystone Master requirement stayed identical: the same ten dungeons, +15 or higher, timed, before the season closed in the summer of 2019 when Season 3 began.
Like Season 1, it is a Feat of Strength now. Seasons 3 (Beguiling) and 4 (Awakened, with the two Mechagon wings added to the pool) followed the same pattern, each with its own Keystone Master entry.
Can you still get BfA Keystone Master?
No. All four Battle for Azeroth Keystone Master achievements moved to Feats of Strength when their seasons ended. The BfA dungeons can still be run at Mythic difficulty (and some returned briefly in later expansions' rotating dungeon pools), but the seasonal achievements themselves are closed and no run today grants them.
If a profile shows a BfA seasonal KSM, that character earned it during the live window. There is no catch-up path.
How does the current Keystone Master achievement differ?
Modern Keystone Master is rating-based rather than dungeon-by-dungeon. Instead of one +15 in each dungeon, you need to reach a Mythic+ rating threshold across the season's pool — in the current season that is 2,000 rating — and the reward is a seasonal mount, which BfA never offered. Rating counts your best runs on both Fortified and Tyrannical weeks, so your total climbs steadily rather than flipping on a single clear.
The practical upshot: today's KSM is more forgiving about a single dungeon you hate, but it asks for consistent timed keys across the whole roster.
What did a +15 in BfA Season 1 actually feel like?
At Season 1 gearing, +15 was the point where trash pulls stopped being forgiving. Infested added split-and-multiply mechanics to certain packs, and dungeons like Shrine of the Storm and Kings' Rest punished loose interrupts hard. Most groups that finished the achievement did it with a fixed roster in the second half of the season, once weekly chest gear had caught up.
If you would rather have vetted human players carry the heavy lifting on today's equivalent, PewPewShop runs Keystone Master progression help (2,000 rating, from EUR 139.99) and single timed +10 keys (from EUR 19.98) in Self-Play or Piloted format, with coaching available if you want to learn the routes rather than just collect the achievement.
