I'm playing an Inquisitor and looking at my options for magic weapons. At the moment I'm at 4th level, and don't have one yet so I don't have to decide in a hurry. (Scabbard of Vigor is my friend.) I'm considering getting a Vicious weapon and using my Fast Healing judgement to alleviate the damage from using the weapon.
The question is: what happens, exactly? Would the Fast Healing occur before or after my attack action? Or would that be up to me?
