Strange Eel is a Fontaine Hidden Gimmick in Genshin Impact 4.1. This guide includes all Strange Eel locations, how to clear challenge, rewards, and more!
Strange Eel - Locations & Map Guide
Attack The Bubbles With Any Underwater Abilities
You need to use the underwater abilities you can adsorb from Xenochromatic Creatures to break the bubbles around the Strange Eel. Any of them will work for this.
You Also Need To Attack Them In A Pattern
Some locations have two Strange Eels around them. You will have to attack them at the same time to clear the challenge and collect the chest. The Jellyfish ability is the recommended ability for this since it creates a huge explosion.
Strange Eel - Rewards
Get Common / Exquisite Treasure Chests
When you clear the Strange Eel, a chest will appear. The type you get is dependent per location.
