Quick Links
The Underground Region can be accessed by traveling through one of the wells scattered around the world ofElden Ring, or by using a certain teleport waygate. There are three main sections in the Underground Region, which areDeeproot Depths, Ainsel River,andSiofra River.
Exploring inElden Ringcan get complicated at times due to its massive world and the sheer amount of bosses. Additionally, players tend to focus more on the upper-ground bosses like Rennala and completely forget that there’s an underground area that’s filled with equally important bosses like Mohg, Lord of Blood.
Updated on June 17, 2025, by Nahda Nabiilah:Although there are a plethora of bosses found roaming around the Lands Between in Elden Ring, players will soon discover that there are even more bosses located in the underground areas. Mohg used to be an optional boss until the Shadow of the Erdtree DLC was released. Now, you can only access the Land of Shadow after defeating Mohg, Lord of Blood.
