K'aresh has one dedicated delve, Archival Assault, added with The War Within patch 11.2 (Ghosts of K'aresh) when the Ethereal homeworld opened. It runs on the standard delve rules: solo or a group of up to five, Brann Bronzebeard as your companion, difficulty Tiers 1 to 11, and a Bountiful version that hands out gear once you spend a Restored Coffer Key on the final chest.

Where is the delve in K'aresh?
Archival Assault sits in the built-up Ethereal part of the zone rather than out in the wastes. Open the K'aresh map and look for the delve icon (the small cave-style marker with a number over it). If you have not unlocked flying there yet, the ground route is straightforward because the zone is compact compared with Khaz Algar's larger regions.
The delve itself leans into what makes K'aresh different: Ethereal archivists, void-touched enemies and a layout that rewards clearing methodically instead of pulling the whole floor. Expect Brann to take more damage here than in the older Khaz Algar delves if you are running him as a healer at low level, so a tank spec or a well-levelled Brann makes the higher tiers noticeably smoother.

Same as every other delve. Tier 1 is a warm-up. Tier 8 is the practical ceiling for gear because the Bountiful chest at that level gives the best item track a delve can drop. Tiers 9 to 11 add scaling and extra affixes and are there for people who like the pressure or want the tier achievements.
Restored Coffer Keys come from weekly delve activities and the key fragments you pick up around the zone. Each Bountiful run burns one key, so plan them: pick the delve whose loot table matches your slot needs rather than spending keys on the first Bountiful marker you see.
Are K'aresh delves still worth running now that Midnight is out?
Yes, for specific goals. The delve is still open and still fun, but current-season delve rewards now come from the Midnight delve pool, so Archival Assault is the place for The War Within achievements, transmog and story completion rather than for competitive gear. If your aim is the best delve gear this season, put your Restored Coffer Keys into the current delves instead.
One honest note: delve content keeps shipping after any single guide is written, so if you have seen a second K'aresh delve name that is not covered here, it may simply be newer than what this article can confirm.
What should I bring before I go?
- Brann levelled and geared for the tier you are attempting; his curios matter more than most people think.
- At least one Restored Coffer Key per Bountiful run you plan to do.
- A self-heal or defensive rotation you actually use; K'aresh enemies punish standing in effects harder than the older delves do.
- The Ethereal-themed zone quests done first, because a couple of them route you past the delve entrance anyway.
