Webspinner Shamans are the rulers of the stalktribes of the Spiderfang Grots as well as the heart and soul of the Spider-God's cult. They are the mortal conduits of the Spider-God's will and their word is the law for Spiderfangs. While this can be inconvenient due to their deranged rantings, Spiderfang Grots do not question them. 
These ranting spellcasters encourage small venomous spiders such as purple skullbacks to nest in crannies behind their ears, between the toes or even in the shaman’s mouth and the Spider-bites infuses their blood with hallucinogenic toxins that allow them to experience visions from the Spider God, and to enter the Arachnarok nests without danger. It also enhances their magic with arachnid energies, allowing them to inject many-legged haste into their skittermobs, conjure wind-blown shields of magical webbing to protect their warriors or summon deadly flesh-crawling spider swarms. 
They are driven by a desire to please the Spider God for which they seek to bring about the Everdank, so that all of its arachnid children can hunt forever amidst the twilight shadows. This alongside the constant need to appease the hungry Arachnaroks makes Webspinner Shamans warlike leaders and they personally lead many battles.
