Rage is a focusing of the power anger and determination that arises during a combat situation. Very hard to train unless in combat due to some things being more of a feeling. Typically users can amplify their anger and fury to a point where they can become physically stronger, sometimes providing a power boost of 2x or 3x. They can have a near endless supply of stamina but this rage can come at a cost, leaving the user sometimes severely weakened and possibly unconscious for several days at a time.
Training: Training usually occurs within combat, very little can be learned from a book.
