The Glowing Sword (also known as the Lightning Sword) is a weapon found by the Sandwraith in the mystic caves during the events of Warrior Within. It is the most powerful secondary weapon available to the Prince. Because it is unbreakable, it is then used until the end of the game, unless thrown. This sword is very useful against one of the final bosses: Kaileena or the Dahaka, depending on which ending you chose (the ending depends on the gamers choice to get the Water Sword or not). Its only downside is it causes damage to the Prince for every time he hits an enemy with it. This sword bears a strong resemblance to the Eagle Sword, the Prince's first primary weapon.
