< X-Blades
Head up the flight of stairs to the top and a single Dark Guardian will appear. The only to combat this being is to use light spells, preferably the Ray of Light. Also stay on the move to avoid its violet ray blasts as they can pass through walls. When struck a few times, it will sent several Dark Elementals. Although they do little damage, they attack in clusters that will hit one-by-one. It will do no good to just avoid them as they will follow until thet hit their target. After a few more hits the Guardian will split into several Elementals. Use the Ray of Light on a few, forcing them remerge into the Guardian. Once the Guardian is defeated collect the leftover items and exit the area.
