You can buy fistech from colemann in the hairy bear inn (usually at night) or wander around the city at night and find any salamandra's, kill them, they often have fistech in their inventory.
Have you been doing the autopsy to the prisoner?
Tell the result of the autopsy to Raymond, he'll tell you what to do next, and eventually give you the last sephiroth to open the tower mage in the swamp.
It'll be good if you check the crypt on vizima cemetery, there's something that will uncover Raymond identity.
