Bow

The Bow is a recurring weapon in the The Legend of Zelda series. The Bow is quite often Link's chief projectile weapon, and often has twice the attack power of the first sword in the games.

The ammunition for bows are Arrows, which often come with various enchantments, such as Fire, Ice and Light. There also exists a special kind of arrow known as the Silver Arrow, whose silvery arrowheads have the power to slay Ganon. Sometimes, arrows can be used in conjuntion with Bombs to create Bomb Arrows.

The Legend of Zelda
The Bow is found in Level 1 (Level 5 in the second quest). Interestingly, rather then having an arrow supply, Link's Rupees are depleted instead of arrows when he fires his Bow. However he must first buy arrows in a shop before he can use them. In the final dungeon, Level 9, the more powerful Silver Arrow can be found, which is necessary to finish off Ganon.
