Although Cerberus isn't very big, he could be dangerous anyway, so you raise your sword and shield to challange him. As soon as you do this, he shoots out three gigantic plumes of fire out of all three of his mouths, which quickly merge into one. Then, the fire strangely splits and forms a "window" around you, so you are not engulfed by the raging flames, but they surround you on three sides. Then the roaring flames die down.
