Elite Combustive Zombie

CREATURE 9
UNCOMMONMEDIUMEVILFIREMINDLESSUNDEADUNHOLYZOMBIE

Variant sulfur zombie

Glowing with a dull amber light, these odious creatures spawn from a combination of necromancy and fire. These destructive creations sow chaos and demolish fortifications, making them the bane of besieged cities.

Necromancers most often create these mindless undead as obedient, expendable servitors. Left to its own devices, a zombie seeks only to consume the living, stopping only when its rotting body can no longer hold together.

Death Throes

When a combustive zombie dies, its body explodes in a 30-foot burst of fire and debris that deals 3d10 + 2 bludgeoning damage and 3d10 + 2 fire damage to each creature in the area (DC 26 basic Reflex save).

Void Healing

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Speed 30 feet
Melee Fist +22 (unarmed), Damage 2d6+10 bludgeoning plus 1d6 fire plus Blinding Sulfur
Blinding Sulfur (incapacitation)

A combustive zombie burns with putrid inner fire. A creature hit by a combustive zombie's fist Strike must attempt a DC 27 Fortitude save. On a failure, the creature is Blinded for 1 round, or for 1 minute on a critical failure.
