The Arms Scroll (武術書 Bujutsu sho, lit. Martial Arts Manual) is a Stat booster that debuts in Fire Emblem: Path of Radiance. When used, the Arms Scroll increases the Weapon Level by one rank, depending on the type of weapon that they have currently equipped. Caution should be exercised before using the Arms Scroll, as one could potentially upgrade an unintended weapon level by accident, simply because the wrong type of weapon is equipped at the time of use.
