Carrion cloud

So I did a monster based on a couple paintings by a friend and former co-worker of mine. Nikki's art is full of gameables and I'm going to plunder the hell out of her portfolio for ideas. Starting with this one. The carrion cloud is one part this painting, another part the living mirage from Pathfinder's Bestiary 5, except more of an asshole.

Overactive imaginations can perceive familiar shapes and forms in the clouds above. This much is known. Some clouds are even remarkable in how much they resemble an animal or a person. However, if a cloud above resembles a creature that has gone missing, there is a possibility that what you're looking at is a carrion cloud. Carrion clouds aren't clouds at all. They're massive, translucent, flying oozes that happen to resemble clouds. They're voracious carnivores that rest in the sky and only descend upon land to track prey. They prefer to hunt at sunset, for when they consume their victims, the blood soaks through their translucent mass and temporarily stains them red. Carrion clouds then hide in front of the setting sun, to avoid detection.

Carrion clouds have a broad migration route, racing alongside the clouds. While carrion clouds do not derive sustenance from actual clouds, they still consume them to gain mass. For unknown reasons, carrion clouds have a tendency to take shapes that resemble creatures they've recently ingested.

Engulf (Ex): A carrion cloud can engulf foes (as per the universal monster ability). A creature engulfed by a carrion cloud can move normally and is not in danger of suffocating, but as long as it begins its turn engulfed, it's subject to cloudgaze in addition to the damage the attack causes. The save DC is Strength-based.

Driplash (Ex): A carrion cloud can shoot an acid tendril as a standard action in a 30-foot line or flood acid as a 10-foot cone. Creatures in the area must succeed on a Reflex Save of 21 (DC 10 + ½ carrion cloud HD + carrion cloud Con modifier) or take 2d8+4 points of acid damage.

Cloudgaze (Ex): A carrion cloud's chemical makeup creates feelings of warmth and euphoria to creatures that come in contact with it. Creatures must succeed on a Fortitude Save of 18 (DC 10 + ½ carrion cloud HD + carrion cloud Dex modifier) or become euphoric for 1d6 rounds. This is a non-magical mind-affecting effect that is otherwise identical to euphoric tranquility.

Gaseous (Ex): A carrion cloud has a body composed of transparent mist. It can pass through small holes or narrow openings, even mere cracks, but cannot enter water or other liquid. It has no strength score, and cannot manipulate objects as a result.

Imperceptible (Ex): A carrion cloud is practically invisible though the air it occupies shimmers faintly. Before a creature can attack it, it must succeed on a DC 20 Perception check. Once passed, the carrion cloud can be attacked by the creature for 1d6 rounds. The carrion cloud loses this ability after ingesting a creature as it turns dark red.

Vulnerable to Wind (Ex): A carrion cloud is treated as a Small creature for the purposes of determining the effects high wind has upon it.
