What you have to do is that you have to D2R Items go in and discover the purpose, which is really fun. Dungeons are actually a part of the game and play perfectly into our final battle.

There are not only the dungeons you're in while you're playing the campaign on a regular basis for say, new gear or a certain thing however, at the end the game, suddenly you're dealing with Nightmare dungeons.

When you're playing the final actions, where more choices is made available via the whispers that surround the Nightmare Dwarf is a dungeon that's now expanded to the Paragon system, which we've shared some glimpses of in the video there.
 
You can enhance the dungeons with these sigils to make them Nightmare dungeons. Then they get more dangerous. Affixes add additional protection to the dungeons, which makes the monsters more deadly or can give you advantages.
 
There's a broad selection of sigils with all kinds of different affixes on them. There's also, again the option for players to choose the types of sigils that you'd like to use. If you come across an sigil that's intended for the wrong dungeon, or one that you consider suitable for your particular class, leave it out and try a new one.

We now have Nightmare dungeons. They're similar to running the Rift in a sense, however it is a bit more distinct and has a sense of buy D2R Ladder Items place.
