The Feather Blade (フェザー ブレード Fezā burēdo?) is an object that appears in Sonic Boom: Rise of Lyric. It is a feather-shaped sword that can create powerful gusts and is one of the weapons that can be used against enemies in gameplay.
As its name implies, the Feather Blade resembles a sword shaped like a large white feather with a black tip, no guard, and a golden ring for a sword pummel. It is created from the feathers belonging to the birds of legends that are said to have lived in ancient times.
The Feather Blade can be found at fixed points throughout the game. When used, it releases a gust of small energy feathers that damage enemies. While this weapon is weak, it has a long range.
