Art of War

Art of War (孫子兵法, Chinese: Sūn Zǐ Bīngfǎ; onyomi: Son Shi Heihō) is a historical document authored by Sun Tzu. It is one of the seven military classics of ancient China and one of the most translated within the seven texts.

The scroll appears in the Dynasty Warriors series as an unlockable item. When it is equipped, it can double the length of time for temporary stat boosting battlefield items. Depending on the game, it adds an extra fifteen seconds to the usual time limit (such as in Warriors Orochi 3).

Dynasty Warriors: Online renames it as "Time Scroll" that adds an extra five seconds to temporary buffs. The upgraded version, "Eternal Scroll", adds ten seconds.
