What the achievement asks
Complete all thirty-one Abominable Stitching quests. Ten points, account-wide.
This is the single slowest thing in the Shadowlands meta, and it is the only piece still on a weekly lockout. Everything else that used to be weekly, the Ember Court included, has since been changed to daily. This was not.
Start it first. Whatever else you do with Shadowlands, start it first.
Why it takes so long
Each construct you have built offers one quest per week, chosen at random from its own small list. You cannot pick, you cannot reroll, and a construct with four quests will happily give you the same one three weeks running.
The quests also appear to be the same across a region in a given week, so there is nothing to gain by asking around.
Five weeks is the lucky case. A month or more waiting on one straggler is common, and Shinies of Bastion and Hands on Approach are the two people name most often.
Which construct gives which quest
Build a construct and its quests enter the weekly pool. This table is the whole strategy: the constructs at the top pay for themselves fastest.
| Construct | Its quests |
|---|---|
| Chordy | Shinies of Bastion, Things They Leave Behind, A Bountiful Haul, Something Old Something Used |
| Atticus | Asset Extraction, Supply Chain, A Brokered Deal |
| Marz | Field Training, Arboreal Tactics, Training Program |
| Mama Tomalin | Baker's Dozen, Give A Dog A Bone, Pie Not? |
| The Professor | The Two Sides of History, Scrounging for Scrolls, One Lich's Trash... |
| Sabrina | Fighting Words, The Last Word, Say The Magic Words |
| Guillotine | Grinder, Hands on Approach, Cut 'Em Down to Size |
| Roseboil | Cure For All Ills, In A Bad Light |
| Toothpick | Old Stomping Grounds, Digging Around |
| Gas Bag | Herbicidal Tendencies, Special Formula |
| Flytrap | Corpse Run |
| Iron Phillip | Bring Your Own |
| Naxx | Drink to the Dead |
The order to build in
Superior Parts are the limiting resource, so build in descending order of quests gained per part spent: Chordy, Atticus, Marz and Mama Tomalin, Roseboil, the Professor, Sabrina, Flytrap, Toothpick, Gas Bag, Guillotine, then Iron Phillip and Naxx.
Flytrap is worth pulling forward if you prefer certainty, because it only has one quest and therefore never wastes a week rolling something you already have.
The constructs themselves are also all sixteen criteria of The Gang's All Here, so none of this building is spent twice.
Where the parts come from
Superior Parts come from your Scouting Table missions, and Malleable Flesh drops from Shadowlands mobs generally. Keep every one you find.
The best concentrated source people name is the House of the Chosen in Maldraxxus while the world quest Chosen Champions is up, because you can keep joining groups running it and farm the same mobs repeatedly.
