Instructions
Complete the level called "The Lair of the Titan." You will leave the area by flying off on the back of a Pegasus and begin the journey to the Island of Creation. Hold "L2" to use your magic to shoot at any harpies that approach you.
Press "Circle" to grab the harpies and throw them out of the sky. Press "Square" or "Triangle" to perform a light or heavy attack on the harpies. A sentry will approach your position after the harpies have been defeated. Press "Square" to weaken the sentry and then press "Circle" to defeat the sentry when prompted.
Shake the analog stick left and right if the sentry jumps onto the back of your Pegasus. Continue attacking this sentry until he is defeated, then repeat this process for a second sentry. This will lead to the boss of this section, the Dark Rider.
Move the joystick up or down to avoid the Dark Rider's ramming attack. Move away from the Dark Rider when he swings his spear and when he uses his spear to fire an energy attack. Move to either side when he shoots fireballs at you, then quickly catch up to him and attack him.
Attack the Dark Rider by pressing "Square" until he is weakened while avoiding his other attacks. Eventually he will fire five waves of fireballs at you that you'll have to dodge. Dodge left for the first wave, down for the second wave, right for the third wave, up for the fourth wave and left for the fifth and final wave. This will trigger a final sequence where you'll have to match the buttons as they appear on the screen to defeat the Dark Rider. Once the fight it over you'll land on the Island of Creation.
