Working out how to unlock Undertaker in Elden Ring Nightreign is actually a lot simpler than it was for previous characters like Duchess. This nun is set to be one of the most powerful characters in the game alongside Wylder, entering a state where she can surge-sprint without consuming stamina as well as get an enhanced dodge.
She can also use her art whenever another character uses theirs, which is pretty cracked if I'm frank. You'll need to unlock both Undertaker and Scholar, as well as defeat two Nightlords (including Gladius), if you want to access the new Balancers boss and The Great Hollows Shifting Earth event, so you'll need to do this first before you can start Forsaken Hollows properly.
