Critical Point

A Critical Point is a narrow space of time where Link has the opportunity to inflict major damage on a dungeon boss, usually with the aid of the Ordon Sword or the Master Sword; only seen in Twilight Princess. Critical Points occur in every temple boss battle except for that of Blizzeta in the Snowpeak Ruins. Usually after required steps have been completed, the temple boss will become tired, expose a weak spot, or faint, giving Link a much needed chance to strike with his sword. Critical points in boss battles are denoted by a change of music, shifitng from the common mysterious boss music to that of a more triumphant nature.

 * Twinrova: in her second form, hit her with her own elemental attacks and she will come down to the ground

Blizzeta in the Snowpeak Ruins does not give Link a chance at a critical point because in order to destroy the Twilit Ice Mass, only the Ball and Chain can be used, not the sword.
