Power Augmentation

Power Augmentation is the ability to enhance the powers of others.

Characters with this ability

 * Lucifer- Lucifer's presence on Earth greatly enhances the powers of Jesse Turner, to the point of being capable of wiping out the Host of Heaven.

Objects with this ability

 * Souls- Souls can enhance powers, predominantly the powers of Angels. 50,000 souls gave Castiel enough power to banish Raphael, while 30-40 million souls from Purgatory gave him the power to destroy not only him, but every angel in Raphael's faction. Tamiel was enhanced to the point of holding off Castiel and the Winchesters, despite Dean possessing the Mark of Cain at the time. Souls can also improve spells, such as the time travel spell Henry Winchester used to get to the future. As a result of being mixed with grace, the souls of Nephilim greatly enhances their powers, making them superior to Angels.
 * Demon Blood- Demon blood can enhance the powers of a special child, allowing Sam to kill not only Alastair, but even Lilith, albeit exhausting him.
 * The Word of God- The angel tablet gave Metatron god-like powers, such as blowing out holy fire, creating objects, and enhanced his strength to easily fend Dean, despite being armed by the Mark of Cain and The First Blade. While never displayed, it was stated by Kevin that the demon tablet could do the same for Demons, giving them great power.
