An adult ettercap stood 6 ft (1.8 m) tall and weighed 200 lb (91 kg). Ettercaps resembled hunched, grey-purplish humanoids with distended white underbellies, spider-like faces (fangs and eyes and such), and two sharp, black chitinous claws instead of hands and feet.
They were not particularly intelligent. They were cowardly and vicious, preferring to set traps to ensnare their enemies. Much like spiders, ettercaps tended to be solitary creatures, only gathering to mate. When ettercaps did socialize, it was with monstrous spiders, which they kept as pets and guards.
Ettercaps possessed the capability to shoot sticky webs. Like spiders, they used webs as traps to capture prey, which was then injected with paralytic venom from the ettercap’s bite.
It was suggested that ettercaps were the descendants of a group of mad druids, tainted and transmogrified by their association with a powerful demon into a form resembling the predatory arachnids their cult once revered. While the vast majority had completely reverted to pure animal instinct, a rare few claimed to demonstrate the intellect and capacities of an insane human.
Ettercaps were very fond of spiders and other arachnids and often kept them as others kept bees. From time to time, however, an ettercap had a number of monstrous spiders as pets, which were as loyal to it as a dog to a human master.
