DnD/Adventures in Rokugan creature: the Kamaitachi

The Kamaitachi, or sickle weasel, is a dangerous and mischievous yokai that lives in the mountains. It flies in on a dust devil, moving so swiftly as to be invisible, and strikes people in the legs with its sickles, knocking them down and leaving deep wounds that do not bleed. They do not kill, and sometimes will even heal their victims before departing. Fairly often, they move in groups of three.
