The
shambler spell creates 1d4+2 shambling mounds with 11 HD each. The creatures willingly
aid you in combat or battle,
perform a specific mission, or serve as bodyguards. The creatures remain with you for seven days unless you dismiss them. If the shamblers are created only for guard duty, however, the
duration of the spell is seven months. In this case, the shamblers can only be ordered to guard a specific site or location. Shamblers summoned to guard duty cannot move outside the spell's
range, which is measured from the point where each first appeared.
