Acid Rainer

**Type:** Elemental
**Subtype:** Air

Acid rainers are creatures of elemental air that live in Earth’s upper atmosphere. They secrete an extremely caustic substance that can eat through flesh and vegetable matter in mere seconds.

Seemingly composed of low-density plasma, an acid rainer resembles a gigantic jellyfish. A dozen or more long, trailing tendrils hang beneath its massive, hemispherical body. Because its entire form is translucent, the few humans who have actually seen one have been unable to describe it accurately, and most have failed to recognize it as a creature at all.

An acid rainer feeds primarily on birds that it captures with its tentacles. Because of its great size and strength, however, it is quite capable of capturing and swallowing humans or other Medium-size creatures as well.

When an acid rainer dies, its body usually decomposes into harmless air long before it hits the ground. In very cold weather, however, a large chunk of an acid rainer’s corpse may freeze and plummet to earth, where it is usually mistaken for an abnormally large hailstone.

Fortunately for humankind, so few acid rainers exist that contact between the species is rare. Even though advancing technology has made it possible for humans to invade the upper atmosphere more and more frequently, the translucent bodies of acid rainers make them difficult to spot. Most verifiable encounters have occurred at lower altitudes, either on very high mountaintops, or when turbulence in the upper atmosphere (such as a windstorm) has forced the creatures closer to the ground. During particularly stormy weather, suspected encounters have occurred at elevations as low as the Smokey Mountains of North America. Such encounters are sporadic, however, since acid rainers have no more desire to stay at low altitudes than humankind has to keep them there.

In combat, an acid rainer attacks with its tentacles, attempting to grab its opponent and haul it into the mouth situated in the underside of its crown. If pressed by a large group of opponents, the creature uses its acid spray ability.

## Special Qualities

Acid Resistance 10 (Ex)
An acid rainer ignores the first 10 points of acid damage from any single attack.
Acid Spray (Ex)
Once every 1d4 rounds, an acid rainer can spray out a cloud of caustic mist that fills a 30-foot radius spread centered on itself. Each creature within this area takes 2d6 points of acid damage, or half damage if a Reflex save succeeds (DC 10 + 1/2 the acid rainer’s Hit Dice + its Constitution modifier).
Acid Touch (Ex)
An acid rainer’s tentacles are coated with a caustic secretion that deals 1d6 points of acid damage on a successful hit.
Elemental
An acid rainer has the traits and immunities common to elementals.
Improved Grab (Ex)
To use this ability, the acid rainer must hit a single opponent at least one size category smaller than itself with two tentacle attacks during the same round. If it gets a hold, it automatically deals damage for two tentacle attacks (including acid) each round that the hold is maintained. See Special Qualities in Chapter Eight: Friends and Foes in the d20 Modern Roleplaying Game for more information.
Skill Bonuses
An acid rainer gains a +8 species bonus on Hide checks and a +4 species bonus on Move Silently checks.
