Object

Wraith-generator called Ghostly Orb.

Object is not one of the three classifications of monsters in Diablo II. All monsters belong to one of the classifications in Diablo II, and certain spells or items are more effective against different types of monsters.

It's not known if these classifications will return in Diablo III, but we're using it since it's a convenient way to sort things, until official information is released.

The classifications of monsters we use in Diablo III are:

• Beasts (category) - Feral, unintelligent enemies. (Called "Animals" in Diablo II.)
• Demons (category) - Mostly Sinister, sentient monsters from Hell.
• Objects (category) - Stationary obstacles, like traps.
• Undead (category) - Varying types of re-animated corpses, mostly from humans.

Objects are enemies, but not really monsters. Objects include things like traps, barricades, monster generators, and more. We have yet to see many more type of "Object" typ enemies in the game.
