Ettercaps are spider-like humanoids with four arms and legs, a carapace, and spider-like faces with fangs and black eyes. They often wield basic weaponry and wear armor or clothing. They are not particularly intelligent. Ettercaps possess the capability to shoot sticky webs, can inject a paralyzing poison from their fangs, and have an affinity for spiders. They are cowardly and vicious, and prefer to set traps to ensnare their enemies.
Ettercaps are very fond of spiders and other arachnids and often keep them as others keep bees. From time to time, however, an ettercap has a number of monstrous spiders as pets, which are as loyal to it as a dog to a human master. Aside from their spiders, ettercaps often live alone (with the exception being an ettercap’s mate). Female ettercaps are more intelligent than the males of the species.
