The archetype is vague, the errata is inadequate, and the full intent is unclear.
Do you still get normal hexes?
Does Extra Hex let you choose hexes like the minor spirit hexes, i.e. choose any from the Witch and wandering spirit list and switch them every day?
What are Minor Spirits? Do they give you anything besides flexible hexes?
While I like the idea of a more flexible, less attached Shaman, I can't help but feel like this archetype is a homebrew cludge. That got me thinking, how would you write up an Unsworn Shaman archetype that was clear, concise and had an acceptable level of power?
