This spell causes instant diminution of a creature or object, decreasing its size and weight. Its height shrinks by up to 10% per caster level, to a maximum reduction of 50%. The reduced weight is proportional to the cube of the new height, as follows:
Height Decrease Weight Decrease
--------------- ---------------
-10% (x 0.9) -30% (x 0.7)
-20% (x 0.8) -50% (x 0.5)
-30% (x 0.7) -60% (x 0.4)
-40% (x 0.6) -80% (x 0.2)
-50% (x 0.5) -90% (x 0.1)
All equipment worn or carried by a creature is reduced by the spell. Magical properties are not decreased by this spell. Weight, mass, and strength are affected, though. A creature's hit points, Armor Class, and attack rolls do not change, but Strength decreases with size. For every 10% of reduction, a creature's Strength score suffers an enlargement penalty of -1, to a minimum score of 1.
A shrinking object may damage weaker materials affixed to it, but a reduced object shrinks only as long as the object itself is not damaged.
Multiple magical effects that reduce size do not stack.
Reduce counters and dispels enlarge.
