Beasts

Animal is 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 three classifications of monsters we use in Diablo III are:

• Animals (category) - Feral, unintelligent enemies.
• 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.

The Animal classification is all monsters that generally seem to be more part of nature or the environment than direct creations of Hell. They are all distinguished by a lack of intelligence, and instead have mostly feral instincts, or basic "hunter" type behaviour. Some of these animals does indeed come from the Burning Hells, however, but they are tools for mayhem used by other Demons.

A few "animal" type enemies can also be humanoid creatures, that are just not demons. Humans are included in that.
