Monster Manual II
Most often, a cloud ray attacks simply because it is hungry. It dives on its prey and tries to snatch it up in its 20-foot-wide mouth, then flies off to swallow it.
In melee, a cloud ray can use its Snatch feat, or it can slap a foe with its tail. When it does the latter, the tail moves so fast that it creates a thunderous sound, like the crack of a whip.
Swallow Whole (Ex): A cloud ray can swallow a snatched opponent that is Huge or smaller by making a successful grapple check (grapple bonus +61). The cloud ray however has no appreciable stomach. Instead it has a long throat, the whole length of which is equipped with teeth for grinding and tearing food. Its throat empties directly into its intestines so the ray must chew its food thoroughly to ensure proper digestion. Once inside the ray's throat, the opponent takes 3d10+22 points of bludgeoning, slashing, and piercing damage per round from its teeth and muscular contractions. A successful grapple check allows the swallowed creature to climb out of the throat and return to the ray's mouth, where another successful grapple check is needed to get free. Alternatively a swallowed creature can try to cut its way out with either claws or a light piercing or slashing weapon. Dealing at least 25 points of damage to the throat (AC 20) in this way creates an opening large enough to permit escape. Once a single swallowed creature exits, muscular action closes the hole; thus, another swallowed opponent must cut its own way out. A cloud ray's throat can hold 2 Huge, 8 Large, 32 Medium-size, or 128 Small or smaller creatures.
Levitate (Ex): The cloud ray controls its altitude by generating and manipulating lighter-than-air gases inside its body. This ability enables it to ascend 20 feet per round or, by neutralizing the levitating gases and letting gravity take its course, descend as much as 500 feet per round. In spite of its immense bulk, the ray can pull out of such a dive instantly simply by levitating again.
Protection from Arrows (Su): This ability allows a cloud ray to resist most ranged attacks. It works like a protection from arrows spell (DR 10/+2 against projectiles), except that the effect cannot be dispelled and it does not discharge after absorbing a certain amount of damage.
Telekinesis (Su): Lacking any sort of hands or paws, cloud ray instead uses telekinesis to manipulate objects. This ability works like the telekinesis spell (caster level 5th) so the creature can lift or throw 125 pounds.
Skills: Thanks to its coloration, a cloud ray has a +16 racial bonus on Hide checks. *When it tires of drifting thro the sky, it settles to the ground for rest. Through a combination of telekinesis and moving its great wing-flaps, it covers itself with dust, dirt, rocks, logs, uprooted bushes, and whatever else is nearby. While it is thus camouflaged, its Hide modifier rises to +32. The ray may rest on the ground thus covered for a few hours or a few weeks.
Feats: A creature that is flung by a cloud ray after being snatched travels 100 feet and takes 10d6 points of damage. If the cloud ray is flying, the creature takes this damage or appropriate falling damage, whichever is greater.
