In Lords of the Fallen, the Umbral is a dangerous location. Whether you chose to go there or were forced into it by enemies, your first objective should always be to get out of there as quickly as possible. The realm of the dead is a place where things can get really bad for you, especially if your Dread gauge fills up with every step you take. Here’s how that works.
Lords of the Fallen: How Dread Works
You can find your Dread gauge at the eastern part of your screen next to your Vigor amount. When you enter Umbral, it automatically fills up, and it takes around 8 minutes to reach full capacity. It usually closes when you’re in the Axion, but opens when you enter Umbral. Exiting the realm through any means (finding an effigy or interacting with a Vestige) will reset it.
