The Light Sword is the strongest secondary weapon available to the Prince and the most powerful weapon in the game with the highest attack power, breakability and attack rate. 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 the player gets.
One hit of this weapon equals 2.5 hits with the Water Sword. Its only downside is the damage it causes to the Prince every time he hits an enemy with it (as noted by the skull next to the stats). This sword bears a strong resemblance to the Eagle Sword, the Prince's first primary weapon.
