Mindless zombies are some of the most abundant monsters in any realm with magic and necromancy. Individually they can do harm but are no real threat to a well armed or armored individual. In numbers they can swarm and become a real threat to even the most seasoned warriors.

Zombies are typically mindless creatures with an inability to reason or plan. They simply exist until food draws near, then they slowly hobble towards it. They have no hobbies or activities besides aimlessly shuffling around with other zombies. They have a tendency to congregate with other zombies, but this is the only sign of intelligence that most zombies exhibit. 

Apparently, there is a rare chance that a zombie will retain parts of their personality and sentience, but it seems to be exceptionally rare.

Zombies have no tactics, they simply move towards any food source until they reach it and then attack or die.

Most zombies can easily be exploited due to their lack of intellect. They can be trapped, corralled and tricked unlike any other creature in existence.

Warriors do not fear a singular zombie. It is grotesque and dangerous but ultimately, easily defeated. They fear many zombies, working together to defeat and consume their prey, they fear zombie hordes.

A zombie horde is any large group of zombified creatures working together to achieve similar goals.

While little is still understood about zombie behavior, particularly zombie horde behavior, some research indicates that zombies are capable of picking up subtle visual cues from other zombies, allowing them to work efficiently together, despite their rotted state.

Zombie hordes utilize almost no tactics and simply charge and swarm any living creatures they see, starting with the closest.

Three things most Zombies lack: Speed, Intellect and Forethought. Because of this, they can easily be led into traps or corralled using living bait.

The swarm can morph and change shape with each of its movements.

Effect: The swarm can alter its shape by up to 6 meters in any direction, including up or down as the swarm forms a tower or ladder. The maximum amount the swarm can morph is limited to the size of the swarm and the shape they are forming. A ladder can be as long as a number of meters equal to the entire area of the size of the entire swarm. A tower is limited in height, in that each additional 2 Meters of height requires that the base underneath it be 1 Meter wider. 

In this way, a Huge Swarm occupying 4 Meters could form a 4 meter ladder or a 3 Meter Tower.
