Spiders are very cautious creatures. They rarely attack until they've attempted to capture their prey in a web. These webs tend to cause stiffness when touched, which either slows their prey considerably or temporarily paralyze them. Fortunately, spiders must rear up on their hind legs to shoot their webs. This is your big hint to get out of the way, which can be done by running to either side of the spiders target area. However the challenge still remains after you've successfully dodged the web.
