Leg-Strength is a skill available in Dragon's Dogma.

DescriptionEdit

"Renders your rank lighter for purpose of mobility."

It makes stamina drain slower when sprinting by a minor amount. The effect is far less then the Dark Arisen augment "Athleticism", that does the same effect to a much more greater level.
It was falsely claimed that this augment had a hidden weight level if you were at very light. This has since been discredited.(source)
