Après six semaines de jeu, j'ai réussi à terminer presque tous les débouchés dans la zone, mais un reste hors de portée. Le problème n'est pas mon niveau de compétence ou ma persévérance, c'est la présence de joueurs de haut niveau qui dominent le lieu. Même quand je parviens à vaincre certains adversaires, ils empêchent que je puisse obtenir l'objectif final. Ce serait satisfaisant de terminer entièrement cette zone.

What platform are you on? If you’re on PS EU, I can join you with some friends to help you get in on the action. Otherwise, the best solution for now might be to move on and return in a few days once the writhing wall event is over. Many players are currently there farming for that event.
On PC EU, but thank you for the offer. I’ve called for help in zone chat a few times when things got tough, and it’s great to see so many helpful players around.
Have you tried asking in zone chat for a group while you’re inside the delve?
Have you tried asking them politely if they would let you have the delve?
To clear the delve and receive credit, you just need to defeat the boss. However, for the achievement, you must collect all seven items: the books and a mossy note.
You can’t kill the boss right now. During the Writhing Wall event, the bosses in delves and public dungeons with blue outlines have been replaced with named Daedric bosses. They can drop special loot, but since they aren’t the true bosses of those delves, you won’t get the achievement for clearing it. It’s annoying, I know.
I’ve only managed a few because they hit much harder than other bosses. I haven’t found anything interesting yet, and I’m not strong enough to farm them. I’m glad I’ll be able to close the gap soon. Thanks!
The delve boss is replaced by a worm cult boss during the event, so the correct boss for the achievement isn’t available. You’ll need to wait until the event ends to complete it.
It’s part of the event. They should still give credit, but some may be bugged. The event will end soon, and once the blue patch behind the icon disappears, you’ll be able to complete it normally. At this point, it’s probably best to wait.
You won’t be able to get the achievement because this delve is marked as “worm cult seized” (notice the blue background on the delve icon). In these delves, the final bosses are replaced by worm cult generals. You’ll need to wait until the wall event ends and the original bosses return.
Have you completed the quest associated with this delve? It’s called Tempting Fates.
To complete a normal delve, you just need to defeat the boss inside.
