Beast Magic

Beast Magic (or Way of the Beast) is a magic that allows to control and tame wild animals. Not to mention about talking with them (or at least gaining some elemental informations, since animal intelllect isn't too sophisticated). Stronger spells allow to tame stronger beings, on gain certain skills from them (like poisonous fangs from spiders, though applying this skill is a tricky thing).
There is also a different route, endemic to areas under Imperial Religion. This magic, sometimes connected with the god(dess) Beast, thus sometimes believed to be a loosely connected theurgy. It allows to permanently change parts of the body into animal ones (like mentioned poison fangs) or even become one.

It is similar to Beast Magic, only concentrated on spiders. Net/thread manipulation, poison using, establishing positive relations with the spiders... even changing into them temporarily/permanently or taking some of their 'skills' permanently.
Its secondary attunement is Poison Magic.
