How to complete the Grachnid Cave puzzle in Brighter Shores

It’s time to resume our adventures in Brighter Shores’ third episode within the Mine of Mantuban. Upon entering the mines, you’ll unlock skills like mining and smithing, with various puzzles sprinkled throughout the region. Here’s how to navigate the Grachnid Cave puzzle to pick up the glowing moss.

How to find Grachnid Cave in Brighter Shores

Grachnid Cave is a region directly southeast of the Mine of Mantuban’s entrance. Its only connecting room is the Kobold Cavern near Upstream Goblin Cavern and the Tenebrous Tunnel, making it easy to access even if you just recently entered the mine.

Unfortunately, there aren’t any portal stones within close proximity of the cave, so you’ll have to run on foot around the tunnels until you reach it. Watch out for enemies like Goblin Miners and Floor Tentacles on your way here!

Brighter Shores – Grachnid Cave puzzle solution

At its core, the Grachnid Cave puzzle involves navigating a hidden maze until you reach the glowing moss stone next to the giant Grachnid. However, if you step on the wrong space, you and the Grachnid will hear a crunch, returning you to the room’s entrance.

Below is the exact route to reach the glowing moss stone.

At first, you’ll head straight up by five blocks until you hit your first wall. You’ll have a few twists and turns from here before stepping across one of the corners and running toward the stone. Fortunately, if you misstep at any point throughout this part, you can return without any penalties.

The most challenging part is the top-left corner space. Making an L-shaped turn doesn’t work here since there are small stones blocking the way. Instead, you’ll have to step diagonally to cross the corner safely.

Once you reach the green moss stone, interact with it to pick it up, bringing you one step closer to completing Mine of Mantuban’s Nullify More Corruption quest.
