"A bow designed for armed conflict. Inflicts more damage than a civilian bow, but it will still burn if it touches fire."
The Soldier's Bow is a bow found in Breath of the Wild. It has a base power of 14 and is typically wielded by Lizalfos and Blue Bokoblins all over Hyrule. It is similar in appearance to the Traveler's Bow, however many more metal reinforcements are present, which signifies a much higher durability rating.
Link can find his first Soldier's Bow in a treasure chest on the Great Plateau, located at the top of the Temple of Time. Link can also acquire Soldier's Bows in treasure chests near a Bokoblin camp north of the Proxim Bridge and in an underwater treasure chest in the South Nabi Lake, just northwest of the Dueling Peaks Tower. Another Soldier's Bow will continuously spawn at the Tabantha Bridge Stable, on top of tarp that covers some crates.
With the power of 14 and decent durability, the Soldier's Bow is a quality Bow early in the game, and a much better option than the Wooden Bow, Boko Bow, and Traveler's Bow, that Link acquires on the Great Plateau.
