What the achievement asks
The nine chapters of the Chains of Domination campaign, the patch 9.1 story. Ten points, account-wide, both factions.
Nothing here is difficult. It is a story you walk through, roughly half an hour a chapter, and the only thing standing between you and the end of it is Renown.
The nine chapters, and what each one waits for
| Chapter | Renown needed |
|---|---|
| Battle of Ardenweald | 40 |
| Maw Walkers | 40 |
| Focusing the Eye | 40 |
| The Last Sigil | 44 |
| An Army of Bone and Steel | 47 |
| The Unseen Guests | 50 |
| The Power of Night | 52 |
| A New Path | 56 |
| What Lies Ahead | 58 |
The first three come together once you are at Renown 40. After that each chapter waits for the next threshold.
Your covenant campaign has to be finished first. If the story will not start, or stalls partway, that is usually the reason rather than a bug.
The Korthia storyline, Shaping Fate, also sits between the early chapters and The Last Sigil for characters coming through fresh.
Renown is the whole timeline
There is nothing to farm here except Renown itself, which means this achievement finishes when Re-Re-Re-Renowned is well under way. Do the two together rather than treating them as separate jobs.
Only worth doing once
The campaign is account-wide and there are no unique rewards for repeating it on another character, no followers and no mounts. The only reason to run it again is the Death's Advance reputation the Korthia quests hand out, and the final quest alone gives 1,500 of it.
