This creature's true name - if it has one - is unknown. It has come to be known by the name "Devil spider" because it certainly is some type of spider, and because it is devilishly evil in its attempts to capture prey and treasure.
The devil spider usually makes its lair in a chasm or large pit, or in an open area near a well-traveled path or under a bridge. It will spin a web which spans an open area (minimum 10'x10', maximum 100'x100') and will then lurk nearby, waiting for a potential meal to arrive on the scene. A spider may attack from ground level, or may descend on a victim from above, suspended by a single strand of webbing material.
The web is made of non-glossy, nearly transparent strands which cannot be detected by torchlight from farther than 5 feet away. And if a victim gets close enough to see the web, the spider will automatically attack. The devil spider will surprise an adversary on a roll of 1-4.
If at least one character or creature is no more than 10 feet away from the web, the devil spider will not usually make a normal attack but instead will attempt to shove the character nearest the web into the strands. If it has a choice, the spider will go for the target which is smallest or looks weakest. On a result of 11 or higher on a d20, this "push attack" will succeed.
The die roll is modified by the following factors:
Target smaller than man-sized: -2
Target larger than man-sized: +2
Target surprised: -2
Target secured in position (using rope, spikes, or other devices): +1 to +4
Target in precarious position (clinging to cliff wall, etc.): -1 to -4
The strands of the devil spider's web are very strong. Any particular strand will be broken only if it takes 10 points of damage in a single round, from one or more hits on the same spot. If a web strand takes less than 10 points of damage in a single round, it will be able to absorb up to 10 more in a subsequent round, because the attacker(s) is not able to hit precisely the same spot with attacks in two different rounds. It takes 40 points of damage to sever a web at the intersection of two strands, where the material is much thicker, but damage to a web intersection is cumulative over more than one round.
Blunt weapons do only half damage to the web. It is fireproof, but takes double damage from cold-based attacks.
The web strands are coated with a clear, glue-like substance. A character whose body contacts the web will be immobilized by the sticky goo, but may pull one or two extremities free. If a roll of d20 is equal to or less than the average of the character?s strength and dexterity (round fractions down), one limb (victim's choice) is freed. A victim can roll to try to partially escape once per round, but no more than two limbs can be pulled loose in this manner. The spider will attack at +2 "to hit" against a victim in the web, and the victim (if able to fight back) will be at -4 "to hit" as long as he is in the web.
A devil spider is reasonably intelligent, and its course of action will always be dictated by circumstances rather than instinct. However, the creature is somewhat predictable. It will always begin a combat situation by making repeated attempts to push a target into its web, as long as a target is available. Then it will assault the victim, trying to kill or weaken it so it cannot escape. During all this time, the spider will generally ignore attacks on its body, but if its hit points are reduced to less than half of the original number, it will either turn to take on the ones doing the damage, or it will attempt to flee (depending on its estimation of the strength of its enemies). After it has captured one victim, it will not attempt to push another one into the web until the first victim is killed or freed.
