Zombie, Black Mold: (aka “moldies”)

Armor Class: 8
Hit Dice: 2
Attacks: 1

Ingredients: black mold

Black mold ‘zombies’ are not actually undead creatures and thus are not true zombies; they cannot be ‘turned’ by a cleric. They are the bodies of dead humanoids animated by a deadly black fungus that grows on flesh. The fungus has a rudimentary intelligence and will seek to infect other creatures in order to spread the colony.
Any creature coming in contact with the black mold zombie (example: being struck by a black mold zombie) or touching a patch of black mold must make a save against poison or become infected with the black mold spores. The mold will consume 1d6 points of constitution per turn after contact; when CON reaches 0, the victim will become a black mold zombie. Torches can be used to burn the mold off the victim (1d6 damage per application). Fire causes x2 damage; cold will cause no damage but will render the mold inert for 1-6 rounds. Because they have no functional internal organs, they take ½ damage from blunt and pierce weapons.
The black mold grows on leather, flesh, wood or other organic substances underground. Daylight causes it to become temporarily dormant.

Zombie, Brain-Eating: (aka “brain eaters” or “mind zombies” or “Virals”)
False Zombie / Brain Eater
No. Enc.: 2d4 (4d6)
Alignment: Neutral
Movement: 90’ (30’)
Initiative: d6
Armor Class: 8
Hit Dice: 2
Attacks: 2 (+1)
Damage: 1d6/1d6/1d6
Special: ½ damage from blunt and pierce weapons, eat brains!
Save: ?
Morale: 12
Hoard Class: None

Ingredients: Brain eating virus (saliva)

Brain eating zombies are the bodies of dead humanoids animated by a virus and cannot be turned by a cleric. Like most zombie class creatures, they are slow moving and often appear as rotting humans. Their usual tactic is to attack with 2 claws, and, if both claws succeed, they will bite for 1d6 damage. Their saliva carries the virus: anyone bitten must save or contract the virus. Failed save means the victim will gradually lose his intelligence (1-6 points per day). When INT reaches 0, they die and become a brain eater.
Anyone killed by a brain eater will have their brains devoured and will arise in 1-6 rounds as a brain eater themselves.
The best way to ‘deactivate’ a brain-eater is to strike it in the head. Criticals scored against them are always assumed to strike the head. Players may elect to strike at the head (for a -2 attack penalty) in order to score +1d6 damage.
Because they have no functional internal organs, they take ½ damage from blunt and pierce weapons.

Zombie, Headless:
True Zombie / Headless
No. Enc.: 2d4 (4d6)
Alignment: Chaotic
Movement: 120’ (40’)
Initiative: d8
Armor Class: 8
Hit Dice: 3+1
Attacks: 2 (hands)
Damage: 1d8 each
Special: Immune to cold and shock, ½ damage from blunt and pierce weapons, 50% immune to criticals
Save:
Morale: 12
Hoard Class: None
XP:
Ingredients: mortified flesh

These look like normal undead zombies (minus the head part, naturally) and tend to be more aggressive (and faster!) than their cranially equipped cousins.
Because they have no functional internal organs, zombies are immune to cold and shock and take ½ damage from blunt and pierce weapons.
They can be turned as 3 hit dice undead.
