What the achievement asks
Defeat the 10 bosses of Castle Nathria, on any difficulty. Ten points, account-wide, both factions.
Castle Nathria is the first raid of Shadowlands, Sire Denathrius's own house in Revendreth. Ten bosses, and the order above is the one the castle imposes: the middle of the raid opens up a little, but nothing lets you reach Denathrius early.
Any difficulty means Raid Finder
This is the sentence worth reading twice, because it is not how the Battle for Azeroth raids work. Three of those demand Normal or higher; none of the three Shadowlands raids does.
A full run through Raid Finder awards this achievement exactly like a Mythic clear. For anyone coming back to the expansion for the meta, that turns three raids from a scheduling problem into a queue.

| 3 | Sun King's Salvation |
| 4 | Artificer Xy'mox |

The three raids of the expansion
All three are needed for the meta, and all three accept any difficulty:
- Castle Nathria, 10 bosses
- Sanctum of Domination, 10 bosses
- Sepulcher of the First Ones, 11 bosses
Raid Finder splits each of them into wings, so none has to be done in one sitting. The wings unlock in order, and the last one holds the boss everybody remembers.
