A Thousand Faces (Su): This mummy king can change its appearance at will, as if using the alter self spell, but only while in its normal form.

Animal Companion (Ex): As a 13th-level druid, this mummy king has an animal companion. The mummy king typically sets this animal to guard a location or object.

Despair (Su): At the mere sight of this mummy king, the viewer must make a DC 18 Will save or be paralyzed with fear for 1d4 rounds. Whether or not the save is successful, that viewer cannot be affected again by this mummy's despair ability for 24 hours. The save DC is Charisma-based.

Mummy Rot (Su): Supernatural disease-slam, Fortitude DC 18, incubation period 1 minute, damage 1d6 Con and 1d6 Cha. The save DC is Charisma-based.

Unlike normal diseases, mummy rot persists until the victim reaches Constitution 0 (and dies) or is cured as described below.

Mummy rot is a powerful curse, not a natural disease. A character attempting to cast any conjuration (healing) spell on a creature afflicted with mummy rot must make a successful DC 20 caster level check, or the spell has no effect on the afflicted character.

To eliminate mummy rot, the curse must first be broken with break enchantment or remove curse (requiring a DC 20 caster level check for either spell), after which a caster level check is no longer necessary to cast healing spells on the victim, and the mummy rot can be magically cured as any normal disease.

An afflicted creature who dies of mummy rot shrivels away into sand and dust that blows away into nothing at the first wind.

Nature Sense (Ex): +2 bonus on Knowledge (nature) and Survival checks.

Resist Nature's Lure (Ex): This mummy king gains a +4 bonus on saving throws against the spell-like abilities of fey.

Swarm Form (Su): This mummy king is able to turn into a swarm of beetles, sand, or scorpions.

The vampire that explodes onto a flock of bats, the mummy that crumbles into a pile of scorpions - these are swarm-shifters, undead that have been granted the dark power to become swarms.

A swarm-shifter appears like a normal undead creature until its body explodes into a swarm. There are many varieties of swarm-shifters, and although some are more common than others, swarm-shifters do not seem limited to certain kinds of swarms by their form of undeath.
