Instructions
Use the Shield spell before the battle begins. Shield reduces the damage you receive by half.
Crouch in the left corner of the screen. This allows you to keep Dark Link on one side of the screen.
Swing your sword repeatedly while crouching in the corner. While Dark Link will block most of your attacks, he will occasionally stand and attempt to stab you or jump and thrust his sword downwards. When he does this, you will hit him with your sword before he hits you.
Use the Life spell to recover your health during battle.
Continue to damage Dark Link until his health bar, located at the left side of the screen, is depleted, leaving you victorious.
