Boss Talents
The achievement that rewards the One Sword Holds Ten Thousand title, earned through the Hero's Realm and Sword Trial bosses.
The structure
The number of bosses can vary season to season. Each boss comes with 3 talents, and each talent has its own set of challenges to complete. Only the first two talents count toward that boss's title — the third talent is a bonus with its own rewards, but never contributes to it, no matter how many of its challenges are done. Within a counting talent, every challenge matters, including its own last one.
How to qualify
Completing every challenge across a boss's first two talents earns that boss's title. Unlike some other seasonal achievements, there's no partial credit at the season level — every single boss's title has to be earned before the season itself counts as complete. Collecting every boss's title in a season earns the One Sword Holds Ten Thousand title, or upgrades its tier if you've already earned it in a past season.
A worked example
A season with 4 bosses — every one of them needs both counting talents fully done, with no exceptions:
| Boss | Talent 1 | Talent 2 | Title |
|---|---|---|---|
| Ashveil Sentinel | 3/3 | 3/3 | Earned ✓ |
| Thornbound Warden | 3/3 | 3/3 | Earned ✓ |
| Gravehollow | 3/3 | 3/3 | Earned ✓ |
| Kindled Choir | 3/3 | 3/3 | Earned ✓ |
Every boss's title earned, so the season itself counts as complete — this is the moment One Sword Holds Ten Thousand unlocks (or upgrades a tier, if already held).
Seasons
Unlike some other seasonal achievements, boss talents never expire when a season ends — once a boss is released, its talents stay obtainable indefinitely, even long after that season is over. A new season brings new bosses with entirely new talents and challenges, tracked completely separately from any past season's. Your tracker page lets you switch between seasons to work on current and past progress separately.
