Arrow of Light
The Arrow of Light is the ultimate weapon for Pit, being one of the Three Sacred Treasures. It's an unstoppable beam of light that pierces through everything in its way, enemy or object alike. The downside is that Pit can only launch one arrow at a time; he cannot fire again until the previous arrow has disappeared.
Appearances
Kid Icarus
This mighty weapon is sealed in a Sacred Casket until Pit assembles all three treasures. In the Palace in the Sky, Pit can blaze his way through Medusa's remaining troops. Its strength is equal to Pit's strength. Even if Pit does not have enough health to use the Sacred Bow, the Arrow of Light will still be able to reach any area of the screen.
Kid Icarus: Of Myths and Monsters
The Arrow of Light is functionally identical to its first incarnation.
Kid Icarus: Uprising
The Arrows of Light return with a brand new design. These holy arrows are fired from an elegant, golden bow, decorated with levitating rays of light.
Super Smash Bros. Brawl
A similar kind of weapon, called Palutena's Arrow, is useable by Pit as his neutral special attack. The arrow can be curved in mid-flight to attack mobile foes (though particularly agile ones can avoid easily), or even looped into a 360 degree angle. It can be charged by holding the B button, but Pit wil eventually fire the arrow automatically. The weapon itself however, is not particularly strong; it lacks knock-out power. On the other hand, Palutena's Arrow can be quite deadly on Sudden Death matches, as it can KO lighter weight characters when fully charged.
