This skull is as large as an ogre and surrounded by buzzing flies. Its bat wings are too small to actually carry it, yet it moves through the air as easily as a bird. It is surrounded by the stink of rotting meat, spice, and perfume.

Creatures that are hit by the Maw’s bite must succeed at a DC 26 Fortitude save or take 1d6 points of Constitution drain. On each successful attack, the herald gains 5 temporary hit points. The save DC is Charisma-based.
Any creature slain by the Maw (including those that die from any of its special attacks or disease) rises 1 round later as a bloody skeleton loyal to the herald.
The Maw is destroyed when reduced to 0 hit points, but it returns to unlife 1 hour later at 1 hit point, allowing its fast healing to resume healing it thereafter. The Maw can be permanently destroyed if it is destroyed by positive energy, if it is reduced to 0 hit points in the area of a bless or hallow spell, or if its remains are sprinkled with 20 vials of holy water.
By using its swallow whole ability, the herald can deal 12d6+18 points of damage to a swallowed creature as if using a slay living spell. A DC 21 Fortitude save reduces this damage to 3d6+18. A swallowed creature must make this save every round on the herald’s turn. The soul of a creature slain by this attack becomes trapped within the herald’s skull (the creature’s body is regurgitated immediately as a mangled wreck of shattered bone and chewed meat). The creature cannot be brought back to life until the herald’s destruction (or a spell deflection-see below) releases its soul. The Maw can hold only one soul at a time. The trapped essence provides the Maw with fast healing 20, lasting 1 round for every Hit Die of the devoured soul. The trapped soul gains one permanent negative level for every round it spends within the Maw--these negative levels remain if the creature is brought back to life (but they do not stack with any negative levels imparted by being brought back to life). A soul that is completely consumed may only be restored to life by a miracle or wish spell. The save DC is Charisma-based.
If any of the following spells is cast at the Maw and overcomes its spell resistance, it instead affects the devoured soul: banishment, chaos hammer, confusion, crushing despair, detect thoughts, dispel evil, dominate person, fear, geas/quest, holy word, hypnotism, imprisonment, magic jar, maze, suggestion, trap the soul, or any form of charm or compulsion. While none of these effects harms the soul, the caster makes a DC 25 caster level check when a spell is deflected-success indicates that the trapped soul is released from its prison and the creature whose body it belonged to can now be restored to life as normal.
Once per round as a free action, the Maw can vomit forth a swarm of maggots (use the statistics for army ants) into a square adjacent to it, after which the swarm moves in a direction of the Maw’s choosing. These swarms persist for 10 rounds.
