The entry in the gear section for books says that they give a boon to skill checks for a specific skill. This sounds very powerful. I am assuming that isn’t a one off boon but stays in effect as long as the PC has the book? Or is a permanent boon once they have read the book maybe?
How is everyone else playing this rule?
I am finding lots of instances where players have access to books in old studies and ruined buildings, so would like to add some books in without it overpowering them. Good to know what anyone else has done.
