The Wild Fairy of Erinnyes is a Genshin Impact quest chain that starts by interacting with a suspicious Stone Tablet in Fontaine's Marcotte Station. The first World Quest in the series is called Foggy Forest Path.
Foggy Forest Path requires you to solve three puzzles using the Xenochromatic Ball Octopus' abilities. It's quite tricky, so follow along the walkthrough below to solve them.
How to unlock The Wild Fairy of Erinnyes quest chain in Genshin Impact
Head to the Marcotte Station in Fontaine to trigger a blue exclamation mark to appear on the World Map. It won't appear when you're too far away from the area. Head to its location by the fountain to find a Carved Stone Tablet, which you must interact with to begin the Foggy Forest Path World Quest—the first part of The Wild Fairy of Erinnyes quest chain.
How to Reveal the altar's secrets in Foggy Forest Path World Quest – Genshin Impact The Wild Fairy of Erinnyes
After accepting the World Quest, follow the quest navigator to the Foggy Forest Path. Once you're in the area, interact with the Mysterious Altar to trigger the quest objective. You'll be asked to reveal the altar's secrets with only a highlighted area in the map to guide you.
This segment involves solving three puzzles in any order. If you don't know how to use the Xenochromatic Ball Octopus' abilities, refer to puzzle #1 below, where the mechanics are explained in detail.
You can find the first puzzle in the northern part of the highlighted area in the mini-map. Refer to the location circled in the image above to find it.
To begin, interact with the nearby machine with a blue ball on top to absorb the Xenochromatic Ball Octopus' abilities. While it's absorbed, the ability will replace your Elemental Skill.
You can switch between the Xenochromatic Ball Octopus' ability and your combat skills by using the special interact button (T for PC; varies per device). While solving the puzzles, make sure you're in the Xenochromatic Ball Octopus mode, which you can check based on the icon of your Elemental Skill button.
Press and hold the Elemental Skill button to continuously fire a water bubble attack. You must target the Contaminated Bacterial Mats (purple rocks) and destroy them using the Xenochromatic Ball Octopus' ability.
After destroying the Contaminated Bacterial Mats, two bubbles will appear in the vicinity. You must press and hold the Elemental Skill button to move one bubble toward the other. Once the two bubbles touch, they will combine and form a bigger bubble.
Next, pay attention to the positions of the three Reed Pipes with runes on top of them. I'm referring to the item the arrow is pointing to above. In this puzzle, all three Reed Pipes have one rune on top of them, so they need to be activated at the same time.
You'll notice that there's a blue barrier surrounding the bubble. Press and hold the Xenochromatic Ball Octopus' ability so that the bubble is at the center of all three Reed Pipes—their positions are indicated by the arrows above. You need to make sure they are all inside the blue barrier.
Once positioned at the center, burst the bubble with a Normal Attack to activate all three Reed Pipes at the same time. A small cutscene will play to indicate you've solved the puzzle. If unsuccessful, try again.
You can find the second puzzle northwest of the highlighted area in the mini-map, by the waterfall. The exact location is circled in the image above. This time, one Reed Pipe will have one rune and two Reed Pipes will have two runes. You'll have to activate them in a specific order, so follow my exact sequence below.
Start by using the Xenochromatic Ball Octopus' ability by pressing and holding the Elemental Skill button to attack the Contaminated Bacterial Mat. When it's defeated, two bubbles and some Slimes will spawn. I recommend defeating the Slimes so they don't get in the way. Use the special interaction button to switch to your normal skills, then switch back to the Ball Octopus' ability.
Like before, press and hold the Elemental Skill button to move the bubble close to the two Reed Pipes with two runes so that the blue barrier encapsulates both of them. Do not move the other bubble.
Once done, use a Normal Attack to burst the bubble close to the Reed Pipe with one rune. When it bursts, do the same for the second bubble. A small cutscene will play to indicate you've solved the puzzle. If not, try again.
The final puzzle is located south of the highlighted area in the mini-map. Here, you'll find three Reed Pipes with one rune, two runes, and three runes. Since they need to be activated by order of rune count, you need to be careful about the positions of the bubbles.
Start by using the Xenochromatic Ball Octopus' ability to attack and get rid of the Contaminated Bacterial Mats. Two bubbles will spawn.
Do not touch the bubble close to the Reed Pipe with three runes. Use the Xenochromatic Ball Octopus' ability to move the bubble close to the Reed Pipes with one and two runes. You need to move the bubble so that it meets the following conditions:
- The blue barrier should encapsulate the Reed Pipes with one rune and two runes, but should not touch the Reed Pipe with three runes.
- The bubble should be closer to the Reed Pipe with one rune.
The ideal position of the bubble can be seen in the image above. Once it's there, use a Normal Attack to burst the bubbles in this order:
- Burst the bubble encapsulating the Reed Pipes with one and two runes.
- Wait for the first bubble to finish activating the two Reed Pipes.
- Burst the second bubble close to the Reed Pipe with three runes.
Once done, a cutscene will play to indicate you've been successful. If not, you can try again.
After completing all three puzzles, return to the altar and interact with the glowing spot to pick up the mysterious item. Doing so will trigger dialogue and complete the World Quest. You'll also unlock two more quests under The Wild Fairy of Erinnyes:
