Nightmares are foul shadowy, non-corporeal creatures that come in different varieties through out the game. They resemble a humanoid figure (that walks on its hands and feet) with a long tail and wide demonic glowing eyes. The one common attribute of all Nightmares is that they are usually hidden and sprout from nowhere to strike at a party.
The higher level Nightmares use Monk or Necromancer melee builds which use holy damage or shadow damage to inflict great harm to a party that is not prepared for them. They are deadly to a party with spell-casters grouped close to each other and not very mobile. It is best if a party spaces itself when fighting them.
Because Nightmares are non-corporeal beings, they are not "fleshy creatures", which makes them immune to Bleeding and against several Necromancer skills targeting flesh, for example Rotting Flesh. Also, they do not leave behind a corpse that can be exploited by a Necromancer.
- Shadow Beasts and Curses of Darkness are members of the Shadow Army which resemble Nightmares, it is not known whether or not they are also Nightmares.
- Only during the Graven Images quest.
- Deep Nightmares and Tears of Dwayna are only encountered in The Aurios Mines, a Challenge Mission.
- Suspected Nightmares.
