Elemental, Acid

About

Acid elementals often appear as still puddles of green liquid that can rise up like a wave, lashing out with acid-dripping tendrils. In the midst of the pool, one can sometimes barely make out regions of darker green that form a vaguely human face.

Acid elementals are almost always encountered in large pools of acid when on the Material Plane and rarely leave these pools when combating foes. A favored tactic is to grab a foe and pull it into the elemental’s acid pool, subjecting it to massive amounts of acid damage.

Nestled among the various elemental there lies a plane composed entirely of acid. It is a place of noxious fumes and roiling, bubbling, pools.

Plane jumpers do well to avoid this place as it is considered by many to be one of the deadliest, if not the deadliest, of the elemental-based planes.

Acid elementals rarely journey from their native plane, except when summoned. They do not like the Material Plane and when called to the place, are usually angered and always a bit uncomfortable. They have no trouble moving on land but prefer the sanctity of their native plane to all others. At rest, an acid elemental is a clear puddle of liquid with a slightly green hue. It can rise up like a wave in a manner similar to a water elemental, or ooze along solid surfaces by sending out tendrils and pulling itself along. Wherever it travels, it leaves behind a shallow trough that emits wisps of smoke.
