Special Attack
Midna brings her hair's hand over her head, twisting the arm like a corkscrew, as a large ball of Twilight magic grows and swirls in the palm. When it has reached sufficient size, she bounces it once and then dunks it down onto the enemies ahead. This attack hits a very peculiar range - a circular area some distance ahead of Midna. Enemies directly in front of her, while hit by the bounce of the magic ball, will not be hit by the blast. The attack carries no Element.

Trivia

 * Midna using Twili versions of wolves to move, attack and run with is a full reference to Midna riding Wolf Link in.
