Weapon type
Might	16
Range	1
Required	Wo Dao
SP	400
Exclusive?	Yes
String ID	`SID_剣姫の刀`
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 Glimmer or Astra.
With 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.

Can be upgraded in the Weapon Refinery. For a list of other such weapons, see list of upgradable weapons.

If unit initiates combat means if the user starts a combat on their turn. The unit does not need to deal damage, nor be the first to attack.
- However, if the effect is applied after combat, the unit must also survive it to fulfill this condition.
The stat increase that can be applied by Vassal's Blade is considered a combat boost.

Vassal's Blade, along with 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.
