Before you is a truly eerie sight; a silver-golden sheet of protoplasm forming rudimentary wings and floating across the chamber, echoing shapes just out of the range of your senses.

Special Abilities
Acid (Ex) An angel jelly secretes a digestive acid that dissolves only flesh. Any melee attack deals acid damage.
Empathy (Su) Angel jellies can detect feelings and intentions in a manner similar to the spell detect good; this is the basic test they use to sense whether something is food or not. Communicating with an angel jelly, such as it is, is accomplished by emotions only, and cannot convey complicated information.
Positive Energy (Su) An angel jelly emits a palpable glow like silver candlelight, and melee attacks and grapples upon it inflict 1d4 positive energy damage; evil beings and undead suffer double damage from this positive energy.

Angel jellies, perhaps the only good-aligned creature of their type, are incredibly rare beings created when an outsider of the angel subtype is somehow killed by an unintelligent ooze, and its spirit is kept from returning to its home plane. The essence of the angel and the admixture of its spirit with the protoplasm of the jelly creates an almost beautiful creature, having intelligence (though of an alien kind) and the will do good, or at least avoid doing harm to good beings. Being oozes and not outsiders, angel jellies have to eat, but their strange senses ensure that they will not consume good beings, though they will eat virtually anything else. They are sometimes used as benevolent garbage disposals wherever they are, which is often a shrine or good-aligned temple or castle. So far, there have been no known examples of angel jellies dividing or reproducing, though they can be killed or starved to death. Some theologically-minded alchemists and wizards would like to study angel jelly specimens, but there are few in dungeon-type settings, and clerics and monks are usually disinclined to allow them to be studied.

The greatest number of angel jellies were formed during the NewGod War, when several cadres of Movanic devas were lured into spirit-warded castles filled with dire jellies and oozes and trapped there, to be changed into angel jellies. These were in turn distributed to temples and shrines dedicated to good, where the seemingly immortal oozes were set as guardians and garbage disposals.
