This guide shares details on how you can complete the 'Reveal The Altar's Secret' objective in Genshin Impact's world quest, 'The Wild Fairy of Erinnyes.'
While exploring the Foggy Forest Path in the Fontaine region of Genshin Impact, you will come across a unique Hydro Tree with an altar at the base.
Upon interacting with it, you will trigger the world quest, 'The Wild Fairy of Erinnyes.'
The first section of the quest, Foggy Forest Path, requires players to 'Reveal The Altar's Secret' without telling much about what players must do in order to progress.
As a result, players easily get stuck in this section of the world quest.
Seeing that, to help players, we are here with a handy guide explaining how you can 'Reveal The Altar's Secret' in Genshin Impact and progress The Wild Fairy of Erinnyes quest.
The Wild Fairy of Erinnyes - Reveal The Altar's Secret
To reveal the altar's secret, you must solve the three nearby Harmonic puzzles. Each time you solve one puzzle, one of the nodes on the tree will activate.
Once you have solved all three Harmonic puzzles, you will complete the objective and will get a new one where you must 'Examine the item at the Altar.'
That being said, keep reading to learn how you can solve these three Harmonic puzzles.
Harmonic Puzzle #1
The first Harmonic puzzle is located on the left side of the altar, as you can see in the above screenshot.
Head there and destroy the Hydro crystal using the nearby orb to remove the infection for summoning the bubbles.
You can find the orb on the nearby pillar. Once you interact with it, you can press and hold the 'E' key to destroy the crystals.
Once you spawn the two bubbles, use the 'E' hold ability once again to merge the bubbles into a bigger one.
As you can see in the above screenshot, you can move the bubbles in a straight line. Use it to merge them.
After that, center the big bubble so that the blue circular line covers all the harmonic equipments.
Once that is done, burst the bubble to release a hydro wave, activating the nearby Harmonics and solving the first puzzle.
Upon correctly solving the first puzzle, a short cutscene plays out, forming a hydro node on the tree.
Harmonic Puzzle #2
The second Harmonic puzzle is located near the waterfall in the Foggy Forest Path.
Head there and destroy the crystals using the orb abilities as you did previously.
Once again, merge the two bubbles that spawn into a bigger one and move it to the center, as shown in the above screenshot, so that all three Harmonics are under the blue circular line.
After that, burst the big bubble to play out the second cutscene, activating the second node on the tree.
Harmonic Puzzle #3
The third Harmonic puzzle is located right behind the altar. Head there and destroy the crystals using the orb's ability.
Doing so will spawn the second bubble, which, this time around, you must place near the two Harmonics, as shown in the below screenshot, with the second bubble covering only one Harmonic near the pillar.
Burst the second bubble and then the first one back to back to solve the puzzle and activate the third node on the tree.
Once you do it correctly, you will activate the final node on the tree, completing the objective of 'Reveal the Altar Secret.'
Head to the altar and collect the mysterious item, which turns out to be a key, finally triggering The Wild Fairy of Erinnyes world quest.
