Sparring Dummy of the Master

This battered wooden dummy is designed for monks to practice their striking and blocking techniques. It consists of a plain round wooden post that stands 6 feet high and 1 foot thick. Six smaller posts stick out horizontally from the post, roughly representing a defending enemy's limbs.
To gain the benefit of its magic, a person with at least one level in monk must train with the dummy 8 hours a day for four weeks. If the training is ever interrupted for more than a 24 hours, she must begin again. If this training is interrupted twice, the monk can never gain the benefit of the sparring dummy.
Once she has completed the required training, the monk is allowed to make a 10-foot adjustment whenever she can normally make a 5 foot adjustment.
