Introduction – Exploring Weavenest Atla and Moss Mother Rematch
Returning to Moss Grotto
Unlocking the Door with the Needolin
Time to check out the locked door in Moss Grotto. So go there now.

Get to the door and play the Needolin.

Entering Weavenest Atla
Activating the Switches
Move to the right and keep going till you reach the chamber with the two switches on top.

Obtaining the Area Map
Hit them both and get the map of Weavenest Atla from the mirror you just passed.

Teleportation Platform
Using the Platform and Resting at the Bench
Go stand on the platform we passed earlier and you will be teleported to the bottom.

Move to the left and rest at the bench.
Breaking the Hidden Wall
Jump into the pond and push through the wall on the left edge. You will go through. Go through this area and clear the path.

Exploring Weavenest
Defeating Mossbugs and Beetles
Kill the small mossbugs and keep moving to the left. You will find a low path with a large rhino beetle blocking the way. Take care of him and go through.

Finding the Mossberry
Explore this area to find a Mossberry in the ceiling.

Clearing the Upper Path
Grab the Mossberry and keep moving to the left. Clear the path in the top left corner and prepare for a boss fight.
Boss Fight – Moss Mother (Rematch)
Main Attack Patterns

She swings down in a low arc that you can jump over.

Soon she will hit the ceiling and now there will be two of them.

They will both occasionally hit the ceiling and drop smaller mossbugs.

Sometimes they will do a combination of mossbugs and stones.

Combat Strategy and Reward
Its pretty much these moves spammed over and over. Not too different from the first time but it can get hectic.
Try to focus fire on one and take it down asap. It’s hard to tell them apart though.
Once they are down you can pick your reward – Weavelight.

Meeting Eva and Crest Upgrade
Reaching Eva
Go back out and make your way back to the bench. Go past the teleportation pad and break the wall on the opposite side. Keep going by breaking the walls down and eventually you will reach Eva.

Upgrading the Crest of Hunter
If you allow her insight – she will evolve your Crest of Hunter. The best crest in the game so far. (Check out our All Wishes guide).

Finding the Rune Harp
Taking the Right Path and Climbing
Head back to the teleport pad and go up. You will find a path to the right.
Collecting the Rune Harp
Go through to the end and go up again up the platforms to find a Rune Harp. This is for the history collector in Bellhart.

Lava Cavern Challenge
Breaking the Wall
Drop down to the bottom and crack the wall in the bottom right corner and go through.
Navigating the Lava Cavern
Follow the path into a lava filled cavern and follow the obstacle course around till you reach the flowers. Use them and the bugs to platform your way to the left.

Collecting the Mask Fragment
On the ledge you will find another Mask Fragment.

Left Path Exploration
Clearing Bugs and Collecting Spool Fragment
Drop back down and head back to the teleportation tunnel and head to the path on the left.

Keep going to the end. Take care of any bugs along the way. At the end you find another Spool Fragment, to increase your Silk capacity.

Leaving Weavenest Atla
Once that’s done teleport back and leave the Weavenest.
Frequently Asked Questions
How do I access Weavenest Atla?
Weavenest Atla is accessed through a Needolin door in the eastern part of Moss Grotto. You’ll need the Needolin ability to play the musical door and unlock access. The door requires Needolin activation each time you pass through.
Where is the Rune Harp in Weavenest Atla?
The Rune Harp is located in the easternmost section of Weavenest Atla. From the teleportation pad, go up and head right. Climb the platforms upward to find the Rune Harp at the top. This item is for the history collector in Bellhart.
How do I beat Moss Mother the second time?
The second Moss Mother fight becomes a dual encounter after she hits the ceiling. Focus fire on one Moss Mother while dodging their low arc swings. Watch for ceiling attacks that drop mossbugs and stones. Staying mobile and targeting one enemy at a time makes the fight manageable.

Eva is located southeast of the bench area. From the teleportation pad, head past the bench and break through the walls on the opposite side. Continue breaking walls until you reach Eva’s location. She offers Hunter Crest upgrades and Vesticrest.
