Rotting bodies, normally slower than the creature they were made from.

You best destroy the head or run away. As the zombie is always on the hunt for flesh and will not stop until they're completely rotted to bone.

We have thousands of stories of the dead returning to hunt the living. To the point where we have zombie survival guides for how to combat them.
The Zombie Survival Guide by Max Brooks is a recommended start to how your characters may survive the story.

None, they are mindless. If they are not made by magic gone ary, the necromancer is giving them direction.

A bit that draws blood. smell of rot, mindless unless given direction.
