Welting Weeping Willow is a Genshin Impact World Quest in The Wild Fairy of Erinnye questline. It unlocks immediately after completing the Foggy Forest Path and involves solving a puzzle with similar mechanics – underwater.
At the start of the world quest, you will be asked to look for a key near the Weeping Willow. Follow the instructions below to achieve the goal.
How to look for the “Key” near the “Weeping Willow” in The Wild Fairy of Erinnyes – Genshin Impact
Follow the quest navigator to the Weeping Willow of the Lake in the Erinnyes Forest region. There is a large area highlighted on the minimap and world map, but that is the goal dive under water to find an altar, along with a puzzle similar to the ones you solved in the Foggy Forest Path.
Swim north of the altar to find one Xenochromatic hunter beam and absorb its ability, then swim to the Fontemer Seaweed, which houses a xenochromatic ball octopus above the altar. Cut the Fontemer seaweed to expose it Xenochromatic ball octopusThen absorb his ability to use in the puzzle.
Swim towards the purple puzzle where you will find two contaminated bacterial mats (purple rocks), similar to those on the Foggy Forest Path. Hold down the Xenochromatic Ball Octopus ability to remove the contaminated bacterial mats, creating a bubble.
Press and hold the Xenochromatic Ball Octopus ability to move the bubble to the exact position shown in the image above. It must include all three pipes, but must be positioned closer to the pipes that have a rune on them. Once positioned as in the image above, pop the bubble with a normal attack to trigger the pipe whistles activation and solve the puzzle.
After completing the puzzle, a Exquisite chest will spawn. After I looted it, interact with the glowing point onto the altar to pick up the item, trigger a dialogue with Pahsiv and complete the world quest.
