Why bloodsworns carry a book that teach Shamanism?

Why are those bloodsworn members carrying a book that teach Shamanism (Summon Briarthorn)?

Isn’t that like blasphemy and punishable by death for them?

It’s part of their community outreach program.


No wonder everyone of them carry a copy of the same book.

Guess they are much more friendlier than what I thought they are.

Should I stop throwing lightning at them and start throwing confetti instead? I am half shaman you know.
