Sir Eddler’s Gem Shop
Eddler has his own shop in Riverside Town, tucked to the side in the central plaza area.

Just look for a big sign of Eddler surrounded by his favorite thing, gems!

Head inside and speak to Eddler behind the counter, and he’ll task Ruffy with finding the Legendary Gems hidden around Riverside.

1.
You are awarded one of the Legendary Gems for helping your fox friend Quintus catalogue all 30 butterflies scattered across Riverside.

If you need help finding all the butterflies and unlocking the Lepidopteran Brother and Lepidopteran Nerd achievements, check out our Ruffy And The Riverside - Butterfly Guide.

2.
One of the Legendary Gems is in the area behind the Serpent Door in the East of Central Riverside.

To learn how to access this area and unlock the Enlightenment! and Big Enlightenment! achievements, check out our Ruffy and the Riverside – Enlightenment Guide.
Once you have access to this cliff-top area, look to the left to see a tree with 3 circles on the front of its trunk.

There are 3 blue, glowing symbols that you need to Swap into the 3 circles on the trunk of the tree.




Once all three symbols are in their spots, a chest will appear. Inside is the Legendary Gem.

3.
You earn this Legendary Gem for helping Oddo in the Etoi Sanctuary clean up all 6 dirty spots across Riverside.

If you need help cleaning all the dirty spots and unlocking the Mr. Clean and Clean Countryside achievements, check out our Ruffy And The Riverside - Dirty Spots Guide.

4.
Head to the northwest corner of Central Riverside, above the forest with the huge trees and Etoi Sanctuary entrance.

You’re looking for a metal door set into the rock wall, it’s on the North edge of the forest area.

The first step is to use your Swap to change the door from metal to wood. This will show that the door has an arrow on it.

Nearby is a block with a downward-pointing arrow on it, use it to Swap the arrow on the door, opening it.

Before running through the door, use your Swap on another block a bit further away that has an upward-pointing arrow on it. Run through the door to appear on a small cliff over the gorge. Use your Swap on the other wooden door to change the arrow and open it.

On the other side of this door is a chest containing the Legendary Gem.

5.
You are awarded this Legendary Gem for helping Jobboo get rid of the bully sharks occupying pools across Riverside.

If you need help getting rid of the bully sharks, check out our Ruffy And The Riverside - Bully Shark Guide.

If you have been following this guide (and any related guides), you should now have all 5 Legendary Gems. Return to Sir Eddler in his shop to hand them over to him and complete his collection.

And with that, you should unlock the Legendary Gems! and More Legendary Gems! achievements for bringing one and all Legendary Gems to Sir Eddler, respectively.
