The Elusis is a strange creature in Zelda Tears of the Kingdom that will give you a nice blue crystal if you hit it with an arrow or any other weapon. But what are these crystals used for?
What are Elusis Crystals used for?
You’ll probably find one or two Elusis Crystals before you figure out what they’re really for. Their only function is to be traded to Koltin, Kilton’s brother. You’ll meet them at Forest Relaynot far from the Ordinn Ravine Tower.
The first time, for the side quest goods, Koltin will only ask you for one crystal and you will get a Bokoblin Mask! The following times, the number of crystals needed will increase and the rewards will change.
Where to easily find an Elusis Crystal?
There is only one place where you can find crystals: by hitting the Elusis! The poor creatures hide exclusively in caves. When you see a blue crystal rabbithit it with an arrow to get a handful of rubies, then follow it into the cave. Search every nook and cranny of the cavern to spot a much larger version, resembling some sort of chameleon, hanging from the ceiling.
Hit him again with an arrow to make him fall. He will then evaporate and return to his rabbit form, leaving behind a crystal.
The interactive map below shows you the exact position of the rabbits but also the caves:
