Aurora

By harnessing natural energy from an aurora and mixing it with their own chakra, the user is able to enter a state similar to Sage Mode. This mode gives the user heightens senses, stamina and healing, among other abilities as long as it is active.

Advantages

 * The user's sense of sight, hearing, balance and touch are increased exponentially.
 * The user's stamina is increased to the point where they don't get tired as long as the Aurora is active.
 * The user gains a healing factor that allows them to quickly recover from even near fatal wounds.
 * Improperly balancing the natural energy with the body's chakra will only make the user sick instead of turning them into a statue.
 * The user can create a special "aurora field" around an opponent that makes controlling their chakra more difficult.

Disadvantages

 * The user requires an aurora to draw natural energy from, making this technique useless at lower latitudes and during the day.
 * Unlike normal Sage Mode, the user does not gain increased strength, speed or durability.
 * The user's Ninjutsu, Genjutsu and Taijutsu are not enhanced.
 * While easier to pull of than in Sage Mode, it is still difficult to draw in the natural energy required to maintain Aurora while in combat.

Trivia

 * This technique is the reason why Hyōgagakure managed to repel an invasion in the past.
