One of the optional and most hidden areas in Elden Ring is the Forsaken Depths. This area is accessible from the lower parts of Subterranean Shunning Grounds.
The Forsaken Depths is home to Mohg, the Omen, and you can get items like Frenzied Flame Seal, Fingerprint Shield, Bloodflame Talons incantation, and the Erdtree’s Favor Talisman +1 from here.
How to Reach Forsaken Depths?
Step outside from the Underground Roadside Site of Grace at the Subterranean Shunning Grounds and walk past the two open doors. Once you cross the send door, drop down the ladder on your left in Elden Ring.
Run past the enemy and take the ladder near the open tunnel end. Once you reach the top, stand on the platform’s edge and jump into the open end of the tunnel below.
When you land inside the tunnel, proceed east. When you find parting ways, follow the path to your north. Here, you will find two paths again, guarded by a giant rat. Kill the rat and take the right end.
Drop down the hole that comes this way, but be careful. An enemy will be waiting below, so quickly move forward. Take the tunnel on your left to exit the tunnel. Now, take the ladder and go down. This area will take you to an elevator in the room’s northeast corner.
This elevator will take you to the Forsaken Depth Site of Grace.
Why come to Forsaken Depths?
Well, Forsaken Depths is an optional area in Elden Ring, and ignoring the entire area won’t matter. There are only two main reasons for coming down into the Forsaken Depths.
Mohg, the Omen Boss
The Forsake Depth area takes you to the Mohg, the Omen boss arena. This optional boss gets you Bloodflame Talons incantation and the Erdtree’s Favor Talisman +1.
Three Finger’s Chamber
If you want to become the Lord of Frenzied Flame, you must locate Three Finger’s Chamber, which is another you come across after defeating Mohg, the Omen. Getting to the chamber gives you the Frenzied Flame ending in the Elden Ring.
