The phoenix spider was created through a mutual effort by the demon queen Lolth and an unknown powerful being from the Elemental Plane of Fire. These creatures now serve both lordlings.
The phoenix spider appears to be a small crimson spider like a black widow, with a black hourglass on the top of the abdomen. They are vicious and attack anything not spider- or flame-like in nature. They can be killed by normal means and take double damage from cold attacks and temperatures. Fire-based attacks of sufficient power (doing damage greater than or equal to their current hit-point totals) will seem to kill them. However, such attacks actually strengthen these creatures, causingthem to reform in three rounds. If slain by other means, it takes nine rounds for these monsters to reform their essences into a more powerful creature.
Only being killed by cold-based spells prevents these beasts from reforming again.

The poison, which is injected with each bite, kills if a save vs. poison is missed; the damage listed is taken for a successful saving throw. In addition, a phoenix spider is able to fire a strand of webbing across a distance five times as far as the spider’s size (i.e., a phoenix spider in its first form can fire a web only 5’ distant, but a seventh-form spider could fire a web up to 100’). One creature may be the victim of such a web-shot, and must save vs. spells as per the magic-user spell web, or else suffer all the usual effects of the spell itself. Note that the webs of the phoenix spider are not flammable.
If a spider has reached its seventh transformation (20’) and it is slain by fire, it reverses its growth process, shrinking one size lower with each death. Any other method of killing it after its seventh life will permanently kill it.
Phoenix spiders are found in various places in the Abyss, and some have been summoned through special rituals by evil drow and human cults. Because they like hot temperatures, these monsters are extremely rare and almost never found away from the place where they were summoned (which is usually kept warm).
