When it comes to grinding dungeons, the rewards can sometimes be useful, but these can often result in stuff that you end up salvaging that has lower qualities.

To get better rewards from dungeons, you can use Nightmare Sigils to alter them, making them more difficult but yield better rewards.

Nightmare Sigils are obtainable once you have completed the main campaign and can be done by doing different activities in Sanctuary.

What Are Nightmare Sigils?

Nightmare Sigils are consumables that can be used to alter specific dungeons, turning them into Nightmare Dungeons when used.

These provide you with better rewards at the end of a dungeon and can be used to alter a dungeon for everyone in the same realm as you.

Additionally, at the end of a Nightmare Dungeon, you can upgrade Glyphs that are placed on your Paragon Board to improve them.

How To Get Nightmare Sigils?

Nightmare Sigils can be obtained initially by completing events, including Legion Events as well as the ones that are available in the Helltide.

Once you have a Nightmare Sigil, you use it to alter a regular dungeon and turn it into a Nightmare Dungeon, which can later provide you with even more of them.

Additionally, you can craft Nightmare Sigils once the option is available at an Occultist once you have obtained enough Sigil Powder.
