Sandy petersens cthulhu mythos 358

IX Mythos Bestiary against the toxic webbing as detailed above A round or two after the pit opens, a large boulder drops down from above to close the pit off, trapping the victim inside This six-foot-diameter boulder (hardness 8, hp 1,080) weighs ten tons, so moving it from below by force is essentially impossible A leng spider can use its webs as cables to roll the boulder aside as a full-round action; at the GM’s discretion, cunning PCs might be able to the same given the right resources and plan Boulder Pendulum (CR 12); Type mechanical; Perception DC 28; Disable Device DC 28; Trigger location; Reset manual; Effect This deadly trap is an example of an exception to the leng spider’s preference for non-lethal traps A boulder pendulum is typically placed in an area of narrow confines, such as along a mountain ledge or in a narrow passage with a tall ceiling When triggered, a large boulder swings down on a thick cord of webbing It makes a +20 melee attack on the creature that triggered the trap and against all creatures in a 30-foot line beyond the initial target On a hit, the boulder inflicts 8d6 points of bludgeoning damage A creature damaged by this trap must make a DC 20 Reflex save to avoid being knocked prone If a creature is knocked prone while on a ledge that is no wider than the creature’s space, it has a 50% chance of being knocked off the ledge Web Net (CR 3); Type mechanical; Perception DC 20; Disable Device DC 20; Trigger location; Reset manual; Effect When a creature enters the trapped location, the trap triggers, causing a weighted net made of toxic leng spider webbing to drop over a ten-foot-diameter area below A creature can attempt a DC 15 Reflex save to dodge out of the net’s way—otherwise the creature is knocked prone, entangled, and exposed to the web’s toxins (see above) Leng spiders are intelligent, carnivorous spiders An adult has a legspan of 20–30 feet or occasionally more, but smaller (younger) specimens are common An adult weighs 1-3 tons Since they never stop growing, a few are far larger Leng spiders are sly and design traps for their prey These can be elaborate and often involve treasure as bait They are clever enough to let some adventurers live after finding the treasure, to entice further visitors to their mountain lairs They delight in preying on humanoid egos and spring traps when a would-be treasure-seeker is most confident Leng spiders thrive on being underestimated Leng spiders have a complex society and are readily able to wage war on those who infringe on their territory Unless in their homes, they rarely fight to the death and will retreat if severely wounded 351
