The Strange Bestiary
A monument spider's legs can stretch almost 500 feet (152 m) from tip to tip. Despite the creature's immense size, its central body remains light enough that it can climb upon and spin webs between orbital elevators, skyscraping arcologies (whether inhabited or, if in a postapocalyptic recursion, long ruined), wizard towers, or titanic marble sculptures.
Monument spiders usually trap prey in their webs like their much smaller cousins do, except the kind of prey they prefer runs the gamut from jet aircraft to dragons. Normally, a monument spider ignores creatures as small as humans, unless those humans become a nuisance.
In a Weird Science recursion, a monument spider might be robotic or alien, or it might look like a normal spider grown several orders of magnitude too large thanks to a radiation leak.
In a Magic recursion, a monument spider might be the mount of a god gone rogue, a war golem, or a creature of myth (in which case, it has a mind and an agenda).
Motive: Hungers for prey, spin webs, self-defense
Environment (Weird Science or Magic): Anywhere on the exterior of massive structures
Health: 45
Damage Inflicted: 12
Armor: 4
Movement: Long
Modifications: Speed defense as level 5 due to size.
Combat: A monument spider's webs are amazingly strong and hard to see at a distance, so they can create a danger zone a mile or more across for swiftly flying creatures and vehicles. Colliding with a web at high speed is not unlike suffering a great fall. It's usually enough to destroy a vehicle and inflict 8 points of ambient damage to passengers or riders (or direct damage to a large creature), and it might move a character one step down the damage track. Any given strand of web is level 4 and is adhesive. Large objects and creatures must succeed on a difficulty 8 Might-based task to pull free, but a human-sized creature (which presents a much smaller body area) must make a difficulty 3 Might-based roll each round to move more than an immediate distance. A monument spider can bite a foe within short range. In addition to damage, the bite delivers a poisonous acid that inflicts 8 additional points of Speed damage (ignores Armor) on a failed Might defense roll.
Interaction: These creatures act like spiders and are either unwilling or unable to communicate. They see characters as inconsequential, a food source, or a danger to be dealt with.
Use: The PCs' flying vehicle or mount gets caught in a monument spider's web strung between two massive structures (or between a structure and a mountain peak).
Loot: Sometimes the useful possessions of previous victims are mixed with the wreckage or bones that accumulate beneath monument spider webs.
GM Intrusion: When the character takes damage from the spider, she must succeed on an additional Speed defense roll. On a failed roll, a particularly sticky web strand adheres to her. The PC is pulled into the air and left hanging on a nearby convenient high point until she can escape with a successful difficulty 5 Might-based task.
