Description Accelerates Special trigger (cooldown count-1). If unit's Spd > foe's Spd, deals damage = 70% of difference between stats. (Maximum bonus of +7 damage. Combos with Phantom Spd.)

Notes[]

  • The maximum Spd difference that matters for Vassal's Blade's damage bonus is 10, due to Vassal's Blade's cap of 7 bonus damage.
  • The minimum Spd difference that matters for Vassal's Blade's damage bonus is 2, which provides 1 bonus damage.
  • The bonus damage from Vassal's Blade is applied after other effects, and is thus not boosted by specials such as Icon Skill Special.png Glimmer or Icon Skill Special.png Astra.
  • With Phantom Spd 3.png Phantom Spd 3, Vassal's Blade will deal extra damage if the user would otherwise have equal or less Spd than the target.
    • This effect stops when the user is regularly 9 Spd slower than the target, as a 1-Spd advantage rounds down to zero damage.

Trivia[]

  • Vassal's Blade, along with Icon Class Green Tome.png Giga Excalibur, which came out at the same time, are the first weapons to come out that may give a damage bonus if Phantom Spd is equipped.
  • With Phantom Spd, Vassal's Blade will deal extra damage if the user would otherwise have equal or less speed than the target.
    • This effect stops when the user is regularly 9 speed slower than the target, as a 1 speed advantage rounds down to zero damage.
  • The artwork of Vassal's Blade is based on the sword Karla wields in her official artwork in Fire Emblem: The Blazing Blade.
