"A hideous and corpulent flying slug-like demon with dual heads.　 Known for its natural invisibility, insatiable appetite, and for flying in ravening packs throughout the Abyss in search of food."

--- Iscladoc the Dark, from his _Commentaries on The Demonomicon_.

Ruzellir are tireless fliers, traversing the Abyss in hunting packs (properly called a "deceit" of ruzellir if they number 8 or more). They are carnivores and prefer to eat prey when freshly killed, although they will scavenge if necessary. Preferred prey include areex, ahulzael, and mephitis, thunder beasts, skurdra, and vrocks. They will attack anything when hungry (90% of the time), and their appetites are voracious and insatiable. They prefer to attack as individuals as long as their targets are S or M sized, and in packs against L-size prey, with 1-3 ruzellir per target.

A favorite tactic of the ruzellir is to latch onto a victim and to fly it into the air (while clawing and biting it, of course), then to drop it from 100-200 feet of height. Deceits are also known to haul huge prey into the air via telekinesis, and to devour it mid-air.

During combat, a ruzell demon can employ only a few at will abilities (one usable per round in addition to its melee attack routine): telekinese 2500 gp weight, fear (by cry---"a sharp, grating howl of lament and rage, like unto a trapped lioness seeing her cubs quartered" according to Iscladoc the Dark), levitate, detect magic, darkness (5’ radius), and gate (45% opening; summons 1-2 ruzellir 70%, 1-3 chasme 20%, 1-3 yochlol 5%, or 1 nabassu 5%).

Ruzellir, although as ugly as Fraz’ himself, are hunted as delicacies by higher demons ("vaguely like squid or escargot, and best served slightly cooked with a pesto sauce" per Iscladoc the Dark). Several demon lords have acquired a taste for ruzellir, including Orcus, Mandrillagon, and Yeenoghu (who also imports them to his plane to maintain a high population for both food and hunting). Outside the court of Pazuzzeus, ruzell demons are rarely employed as messengers, guards, or the like, due to their low intelligence.

Ruzellir may be turned by high-level clerics as a Special undead.
