How to find Dendrograna & get rid of the Withering in The Rhythm that Leads to the Gloomy Path Sumeru World Quest in Genshin Impact
Follow the green traces or the quest marker to the woods, and then use the Vintage Lyre in front of the hollow tree to play the Rhythm of the Gloomy Path: mi > re > mi > re > la. The hollow tree will turn into a portal—enter it to find a Withering Zone.
Start by getting rid of all the enemies and activating the Cradles of Life to prevent being overpowered by Decay. Next, head to the very back of the cavern to find a hollow tree trunk. Like before, use the Vintage Lyre in front of the hollow tree to play the Rhythm of the Gloomy Path: mi > re > mi > re > la. This will open up a portal leading to another cave.
Use the Four-Leaf Sigil to propel to the rock with an up arrow sign. Then glide down to the down arrow sign. Some fungi will spawn—defeat them to activate the Auspicious Branch containing Dendrograna. Summon Dendrograna, then use the Four-Leaf Sigil to go through the hollow tree and back to the Withering Zone.
Now equipped with Dendrograna, shoot the three Withering Branches to summon Marana’s Disciple, as well as other fungi around the Tumor. Defeat all the enemies and interact with the Tumor of the Withering to destroy it. You’ll receive an Exquisite Chest reward.
