Corrosive Web (Su)

2/day, a gloom spider can throw a corrosive web on enemies in a 15-ft.-cone burst. All creatures caught within the cone must make a reflex save (DC 16) or are entangled for 2d4 rounds, but can break loose by spending 1 round and making a DC 20 Strength check or Escape Artist check. The webbed victims take 1d6 points of non-elemental damage per round while in the web. The strands of the web are flammable. A magic flaming sword can slash them away as easily as a hand brushes away cobwebs. Any fire—a torch, burning oil, a flaming sword, and so forth—can set the webs alight and burn away in 1 round. All creatures within flaming webs take 2d4 points of fire damage from the flames. This save is constitution-based. Blue mages may learn this ability as a 2nd level spell (Knowledge: Arcana DC 19).

Critical Attack (Ex)

Once every 1d3 rounds as a standard action, the gloom spider can inflict more pain than normal. If they succeed at hitting with their bite attack, the damage is 1d8+6 x 1.5 for total damage.

Poison (Ex)

Bite – injury; save Fort DC 18; frequency 1/round for 6 rounds; effect 1d4 Strength damage and staggered; cure 2 saves. Save DC is Con-based with a +2 racial bonus.

Strong Webs (Ex)

A gloom spider’s webs gain a +4 bonus to the DC to break or escapes.


A giant spider-type monster that is known for wrapping its victims in silk and storing them in its nest. Often, however, it captures this prey not for itself, but as nourishment for its young. The strong silk fibers from spider-type monsters have been used as building materials since ancient times, but in recent years there is a movement centered in Dilmagia to develop a new type of fiber.
