Ancient Tomb of Nanjo Location and Walkthrough

Descend the exposed staircase entrance into the tomb. Slide through a crack in the wall, pass a sarcophagus, and optionally loot a chest to the left (the objective chest is white when viewed with observe mode, while side chests are gold).

Continue west and use your grappling hook or jump into a pool of water. Climb onto a ledge to the west, descend stairs, climb another ledge, and drop into a chamber with a square pool of water – this is the hub room.

From the hub room, head north and west, then drop into a chamber for the first choice.

First Choice: Take the north slope. Slide down, go west into a chamber split by a pool. Jump across stalagmites to a west ledge, go through a doorway, and drop into a watery pit. Swim south to a ledge, crawl through a hole to emerge in a chamber with two east-rising staircases. Ascend them, go through a doorway, follow winding tunnels to another watery chamber. Look southwest for a ledge with a stalagmite. Jump into the water, swim to the ledge, and climb the stalagmite. Go south through a doorway and drop into the next chamber.

Second Choice: Take the south slope. Loot a chest, then continue down the south slope. You'll reach a watery passage. Look east to spot your destination. Turn west to find a dock, jump onto a stalagmite, then another embedded in a cliff. Follow planks northeast, turn west, jump a gap to a ledge, then jump across planks south. Slide through a crack south to a chamber with a chest. Exit, advance to planks northeast, and use your grappling hook to swing east. Climb up to the east, head uphill to a pool. Climb the cliff in the northeastern corner (not a stalagmite) and ascend stairs. Turn west, drop into a chamber for the third choice.

Third Choice: Take the south slope. Drop into the room with two slopes (south and north). Use observe mode; the objective marker is north, indicating the wrong path. Slide down the southern slope and follow the tunnel ahead.
