From Guild Wars 2 Wiki
Leap and strike your foe. The less health your target has, the more damage you cause.
— In-game description [?]
- Distance travelled by the leap is affected by changes in movement speed, such as from swiftness, cripple, chill, and Signet of Shadows.
- The leap has no vertical movement, making it less than useful for crossing gaps.
- Having the Quickness buff also shortens the length of the leap, because it is performed twice as fast.
