Phantom spiders are unforgiving servants of the drow that were "bred" from more lethal wraith spiders (Source: Monstrous Compendium Annual, Vol. II). As such, phantom spiders are partially immaterial, and easily fade into the darkness, except when they are arroused, their bodies are suffused with a cold witchlight while their eyes gleam with hellish malice.
Phantom spiders spin a foul green-glowing web that drains the very life from those that become ensnared in it: phantom webbing drains 1d4 hit points in the event of casual contact and reqquires a successful saving throw vs. paralyzation to avoid being immobilized for 1d6 rounds. Every round of continued contact drains an additional 1d4 hit points of damage from the cold. The webs only part to silver or +1 or better weapons, although a successful bend bars/lift gates roll will also break a strand.
Development: Note that the spiders' phantom-like substance may prove too much for the heroes' means (phantom spiders can only be hit by silver or +1 or better weapons), so retreat might be the only tactic available (although note the phantom spider's weakness to holy water as described in the stats below). Phantom spiders do not pursue the player characters, unless the characters are accompanied by chitines. In this case, the phantom spider pursues until either it or the chitine are slain.
Phantom Spider (1): AC 5; MV 18, Wb 18; HD 2+2; hp 10; THAC0 17; #AT 1; Dmg 1d4 (bite); SA Poison (see Notes); SD Silver or +1 or better weapons to hit, immune to cold-based attacks, sleep, charm, and hold spells; SW Holy water, turning (see Notes); SZ M (4 feet diameter); ML Champion (15); AL LE; XP 650.
Notes:
SA-Poison. A successful bite delivers phantom venom which remains active for 1d4+1 rounds in the victim. Each round the venom remains active, the victim must make a successful saving throw vs. poison or temporarily lose 1 point of Constitution. A slow poison delays the effects of the venom but does not restore Constitution already lost (but a neutralize poison would do the trick). Constitution returns at a rate of 1 point per 24 hours. Victims drained of all Constitution points die and have a 15% chance of rising again as phantom spiders.
SW-Holy water vials thrown at these creatures inflict 2d4 points of damage (as acid) against their phantom bodies. Because of their shadowy nature, phantom spiders are turned as shadows.
