Despite all correlating sources including the Core Rulebook, Archives of Nethys and every other source not including the Manipulate keyword on the Raise a Shield action, my GM consulted chat GPT (which has been thus far infallible) and it maintains against all argument that Raise a Shield is a Manipulate action that would provoke attack of opportunity. I've been unable to find a source to directly refute the AI so we're stuck with that ruling for the time being. Is there any stated ruling that explicitly states the Raise a Shield action is not a Manipulate action or would logically demand this to be so?
