Keystone Hero: Season Two is the Mythic+ achievement for clearing every dungeon in The War Within Season 2 pool at keystone level 10 or higher — all eight dungeons, +10 or above, finished inside the timer. It rewards that season's Mythic+ title. Rating alone does not unlock it. Season Three works identically with its own dungeon list and its own title.
The TWW keystone achievement ladder
| Achievement | What it asks for |
| Keystone Explorer | Every season dungeon completed at +2 or higher |
| Keystone Challenger | Every season dungeon at +5 or higher |
| Keystone Conqueror | Every season dungeon at +7 or higher |
| Keystone Hero | Every season dungeon timed at +10 or higher |
| Keystone Master | 2000 Mythic+ rating (Season 2 mount: Breath of Blight) |
| Keystone Legend | 3000 Mythic+ rating (Season 2 mount: Breath of Ruin) |
How to finish it, in order
- Check which dungeons you still owe. Any Mythic+ tracking addon or Raider.IO profile shows your best timed level per dungeon for the current season.
- Push your worst dungeons first. One untimed dungeon blocks the whole achievement no matter how high the rest are.
- Time each one at +10 or above. A depleted +10 counts for loot and vault progress, but not for Hero.
- Overshooting is fine. A timed +12 in a dungeon also satisfies the +10 requirement for that dungeon.
Do the runs have to be timed?
Yes, for Hero. The lower rungs — Explorer, Challenger, Conqueror — only need the key completed. Keystone Hero is the first tier where the dungeon timer actually matters, which is why players who already sit near 2000 rating can still be missing it on one or two awkward dungeons.
Keystone Hero vs Keystone Master: which comes first?
They measure different things. Master is a rating threshold (2000), so it can fall out of a wide spread of +8s and +9s. Hero demands a timed +10 in every single dungeon of the pool.
In practice most groups hit Master first and mop up Hero afterwards, usually on the two dungeons their comp hates. Both are worth doing: Master carries the seasonal mount, Hero carries the title.
Is Keystone Hero: Season 3 TWW any different?
Same rule, new pool. Season Three swapped in a different eight-dungeon rotation — including both halves of Tazavesh as separate entries — so the achievement resets and you re-time every dungeon at +10 or higher for that season's title.
Can I still earn the Season 2 version?
Seasonal keystone achievements and their titles are tied to the season named in them. When a season rolls over, the ladder resets and a fresh version replaces it — Midnight Season One is the live one now. If you are specifically after Season 2 rewards, check what a seller currently lists rather than assuming either way.
Does it help my vault?
Indirectly. Chasing timed +10s is the same activity that fills the highest Great Vault slots, so the Hero grind and your weekly gear grind overlap almost completely. That is the main reason people push it even when they do not care about titles.
If the last two dungeons on your list keep eating the timer, PewPewShop runs coaching and play-together sessions with vetted human pros — a timed Mythic +10 in Midnight Season One starts from EUR 19.98, and the full Keystone Master package with the seasonal mount from EUR 139.99. No bots, no cheats, and no pressure if you would rather keep grinding it yourself.
