As its name suggests, it is particularly effective against beast units, which include the following:
- Horse-mounted units (Cavalier, Troubadour, Paladin, Great Knight, Bow Knight, Dark Knight, Strategist)
- Pegasus-mounted units (Sky Knight, Falcon Knight, Kinshi Knight)
- Beast units (Kitsune, Nine-Tails, Wolfskin, Wolfssegner)
The weapon returns in the spin-off title Fire Emblem Warriors, in which only deals additional damage to Cavalry.
Effective against horse and beast units; ineffective otherwise.
