Familiars who take the form of Spiders take a form that is larger than can be found in natural Spiders. Familiar Spiders have a body that is about 5 to 6 inches in length, giving them about a 10 to 14 inch leg span, and they weigh just over a pound. They are able to crawl upon any surface and can spin webs just like any other spider. Spiders are also able to jump up to 15’ in a single bounding leap. Spiders also feel that they are connected to the “web of life” and that allows them to more easily see through illusions. They get a +5 modifier against any roll versus an illusion. Spiders grant their bonded spell casters a +2 modifier to Perception skill rolls and to any rolls against illusions.
