Shambler creates 1d4+2 shambling mounds of 11 HD. (See the
Monster Manual for details about shambling mounds.) The creatures
willingly aid the character in combat or battle, perform a
specific mission, or serve as bodyguards. The creatures remain
with the character for seven days unless the character dismisses
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 spells range, which is measured from the point where
each first appeared.
The shamblers have resistance to fire as normal shambling
mounds do only if the terrain is rainy, marshy, or damp.
