Protector of Facade is obtained by defeating Roc within three and a half minutes. Before you can attack Roc, you have to fight some of his fellow wolves. Use Dark Hand to quickly defeat them. Roc has a pattern of jumping off the rocks towards you, run around a little bit before jumping on the rocks again. Evade the first attack by Roc by evading, use Dark Lance while he's running. If he engages you, use Dark Hand on him. Rinse-and-repeat until he is defeated.
