* [[Demon]]s ([[:Category:Demons|category]]) - Mostly Sinistersinister, sentient monsters from [[Hell]].

The '''Undead''' classification is for several types of [[Undead#Corpse_Types|corpse]] or [[skeleton]] reanimation. A [[Witch Doctor]] or [[Necromancer]] is capable of summoning undead [[monster]]s to help him in battle without touching [[demonic magic]], but the term mostly it refers to enemies of the player. The undead monsters vary greatly in appearance and intelligence.

[[Image:Mon-skeleton3.jpg|thumb|A [[Skeleton]].]]A lot of undead comes in the shape of a [[skeleton]], or a skeletal construct. As necromantic magic works, it doesnreanimated skeletons don't have to be made up of pieces of from one single old skeleton, but it can be made from pieces from a number of corpses. As [[Abd al-Hazir]] says in his [[Writings_of_Abd_al-Hazir:_Entry_no._0008|entry on the Skeletal Undead]], it's up to the [[Necromancer]] or mage that reanimates a skeleton on and how much energy he infuses it with, and the intelligence and power of the skeleton varies greatly. Some are nothing more than a brainless shell, attacking with limbs or simple tools, while others have enough intellect to use more complex tools like bows, and powerful ones can cast spells and even summon additional skeletons themselves, making a skeletal army potentially very powerful.

[[Ghoul]]s are some sort of reanimated corpse but nothing like slow shambling [[zombie]]s; the ghouls are fast and uncanny, running hunched over in a bestial, almost quadrupedal style. They climb quickly and leap out at the player from all angles, seen scaling a huge wall to get into the action. They seem somewhat intelligent in that they can also wield weapons, such as swords.
