The Gluttonous Yumkasaur Mountain King (Kongamato) is a Genshin Impact Normal Boss that drops the Overripe Flamegranate, a character Ascension material for Kinich, Kachina, and potentially other Natlan characters in the future. If you're having trouble finding the boss's lair, follow the steps below to find it.

The Gluttonous Yumkasaur Mountain King is a Dendro Normal Boss that is located in an underground cavern north of the Scions of the Canopy in Natlan. To access the area, start by heading to the location of the boss icon on the world map above ground. You can easily get there from the nearby Statue of The Seven.

When you get there, you will find a group of Tepetlisauri. You have to live with the adult Tepetlisauri to become one.

The Tepetlisauri has a unique ability to enter cracks in the ground or walls. You will find a magma filled crack right in front of you. Enter to reach the underground cavern.
