Animals

Bear in mind that creatures you encounter in the game aren't only Demons. There are few types of animals which resemble demons, but actually arent. Read carefully, for these animals attack in numbers.

Fallen ones are probably the first animals you may face in your quest. Pint sized and weak, they may seem to pose no threat.. but they make up for it with their overwhelming numbers.
