How to Find the Altar of N'Kuhana
In Risk of Rain 2, along with your lunar coins and secret Newt Altars, there lies an even darker secret, the Altar of N'Kuhana. When found, this altar will award you with the Her Concepts challenge and the item N'Kuhana's Opinion. To see the details of that item, head over to the Items and Equipment page.
Finding the Altar
To find the Altar, you will want to complete a run until you reach the Wetlands environment. From there you will want to look for the large L-shaped stone platform near the edge of the map. If you look over the edge you will notice a ledge jutting out from the side.
Take a leap onto the platform and follow the blinking red lights to Altar in the depths below. Once you find the floating skeleton, shoot it and you will complete the Her Concepts challenge.
