A Leg-breaker was someone breaking dog legs during the D'rek festival. The barbaric act involved breaking one of the legs of a dog for it to then be chased by children through the alleys and eventually get stoned to death. Noto Boil was one in his youth which means the tradition was likely based in Kartool but possibly also elsewhere. Noto got paid three crescents a dog. The Malazans eventually outlawed the festival.
