Genshin Impact

Vulpes Zerda Chapter

Jessica Dillon

This quest needs to be completed in order to finish the Sumeru Archon Quest if you have unlocked it before starting Akasha Pulses, the Kalpa Flame Rises. The quest focuses on the Sumeru forest and Tighnari’s investigation into a contaminated zone. Below we go over how to unlock the quest and what you will need to do to finish it.

The Mechanical Crab from Tighnair’s story quest.

How to Unlock

To unlock Tighnari’s story quest, you must have completed The Morn a Thousand Roses Brings, be Adventure Rank 40, and use one story key. To get the story key, you need to complete eight daily commissions and redeem them in your quest menu.


A contaminated area that seems to differ from the Withering Zone is spreading through Avidya Forest, disturbing the thoughts of many who pass through the area.
You take great pains to be fully prepared before you delve into this area, but your hard-come-by guide turns out to be a mechanical crab who cannot communicate with you.
Yet, is any one life greater than another? Perhaps its cold outer shield may yet hide thoughts that shall coalesce into a beating heart.

The Start of Contamination

To start the quest, speak with Katheryne in Sumeru City. After learning that a part of the rainforest is contaminated, you meet up with Tighnari. You will go into town and purchase Vasanti Grass and then question the people around you. Finally, you will learn that a merchant was robbed in the rainforest.

Head to the locations marked on your map and follow the Sumpter Beasts, you will need to feed them after a bit of walking, and afterward, they will take you to a location where a Mechanical Crab can be found. Defeat this enemy and take the components to the merchant in Sumeru City. You will now head back to Avidya Forest where you will cure Yara.

Into the Hinterland

Return to the marked spot on the map where you left the Mechanical Crab. You will go with him into the contaminated region, where you will install a device to purify the area. This will attract some Spinocrocodiles, defeat them, and then check out the nearby area where two Ruin Scouts are attacking a man named Jasar.

After speaking with Jasar, you will set up camp and rest for the night. In the morning, you simply need to pick up the marked objects outside the tent and head further into the contaminated area. You will soon be attacked by more Ruin Enemies. Defeat them to move on to the third part of the quest.

Heart of the Machine

This is the domain portion of this story quest, in here, you will be able to try out and play as a well-built Tighnari. You will need to follow the straightforward path, defeating Ruin Enemies along your way until you find the researcher responsible for the contamination.

After learning that he has died in his lab, collect the three documents around the area and then head to the Ley Line Extractor. You will need to defeat a few more Ruin Enemies, and then you will be able to shut the machine down. You will go back to the lab for a short cutscene before confirming that the Ley Line Extractor is inactive and leaving the area.

Garden Memories

For the final part of the quest, head back to Sumeru City and let Katheryne know that the commission is finished. Afterward, move your clock to between 08:00 and 12:00 the next day. You will now head to Pardis Dhyai to speak with Tighnari and finish up the Vulpes Zerda Chapter.
