There’s an entire underworld in Elden Ring, and just like the surface, it has its own lineup of bosses to fight. There are a total of six between the Siofra River and Nokron, the Eternal City. The full list is below. The bosses are listed alphabetically.

All boss locations in Siofra River
The Battle of the Ancestral Spirits is accessed by examining the Beast’s corpse in the Hallowhorn compound – the location is marked above. Before you can access the battle, you must light eight lanterns placed along the river bank. You can find all locations in this guide. Once they’re lit, you can start the fight.
The Dragonkin Soldier does not require any special activation. Just walk up to it and it will awaken and start the boss fight. You can find it in the northern part of the map, marked above.
Mohg, lord of blood
Finding Mohg involves a few steps, but first you’ll need to reach Mohgwyn Palace – here’s a full guide on how to get there. Once you’ve unlocked this part of the map, follow the path through the palace grounds and mausoleum to reach Mohg in the highest room. Here’s another guide on how to defeat him once you’ve made the climb.
All boss locations in Nokron, Eternal City
To reach Nokron, the Eternal City, head to where the shooting star lands after defeating General Radahn. You’ll be on some rooftops when you first enter the city. Follow them to an aqueduct (marked above) where you’ll encounter the boss on the other side of a foggy door.
Royal ancestral spirit
As with the previous Ancestor Spirit, you access this boss fight by examining another body. This one is on the other Hallowhorn Grounds as indicated in the screenshot above. You need to light more lanterns, so read our guide for more instructions on how to do that.
Brave Gargoyle & Brave Gargoyle (Twinblade)
This boss duo is the last hurdle in town. They are at the end of the aqueduct, at the location in the screenshot above. Once you’ve defeated them, you can ride the coffin into the Deeproot Depths where there are even more bosses to find.
