Wanderer's Crest Location

Farm Rosaries: Find a Bench in Mosshome (up and to the left of Shakra). Exit left to an area with five enemies that drop Rosaries. Defeat them, return to the Bench to rest and respawn (be brought back to life at a checkpoint after death) them. This farming process can take 20-30 minutes to gather 500 Rosaries.

Purchase the Simple Key: Return to the vendor in Bone Bottom with 500 Rosaries and purchase the Simple Key.

Navigate to the Simple Key Door: Go back to Mosshome and find the exit to an outside area with hanging cages. Reach the far left side. You can do this by pogo bouncing off a flying bug to grab the first cage, then jumping left and pogo bouncing off another bug to reach the second cage. Alternatively, from the Mosshome ledge with the Choral Commandment, jump left and land on the first cage, then jump left again and pogo bounce off a bug to reach the second cage. If you miss, momentum may carry you to a fallen cage at the bottom, from which you can climb to the left exit.

Pass the Acid Creature: In the next room, a creature on the ceiling spews acid. Use the platforms for cover (press the cover button to crouch behind walls or objects). Wait for the acid to stop, then hurry to the left and under the next platform. Repeat until you reach the end, hide under the ledge, and rush to the exit when there's an opening. The Simple Key door is now in front of you. You can find a Mask Shard in a secret alcove below before proceeding.

Enter the Wormways: Head to the ledge, avoiding worms from the ceiling, until you see an opening in the ground. Fall down, holding to the sides to avoid spikes and timing your descent with falling worms. Take the exit at the bottom.

Break the Wall: Break the wall to your right to enter a large room with familiar enemies. Ignore the top-right exit and fall to the bottom.

Find the Chapel Entrance: At the bottom, you will land on a bridge or in water. Go right first and destroy the vines covering a bone door to open a shortcut back to Bone Bottom. Then, journey left to a building – this is the Chapel of the Wanderer.

Navigate the Chapel: Be careful of tripwire traps. Go down the right side and a hole will open, dropping you further. Enter the room on the left for a combat arena.

Clear the Combat Arena: Defeat four waves of enemies, including flying bugs and a large rolling enemy. Your pogo/downward air attack is helpful here.

Create a Shortcut and Claim the Crest: After clearing the waves, head left and up, then attack the ceiling to create a shortcut. Return to the bottom, then go right to find an item you can claim. Press the button when prompted to get the Wanderer's Crest.
