Enlarge/reduce

Enlarge person was a transmutation spell that doubled the height of one humanoid with a corresponding increase in mass. Earlier versions of this spell were called enlarge and worked on both humanoids and objects, but to different degrees. Enlarge was reversible, and the shrinking spell was called reduce.

Effects
The transmutation version of this spell instantly doubled a person's height and increased their mass by a factor of 8. All clothing, equipment, and items carried were also doubled in each dimension, but any item that left the possession of the recipient immediately reverted to its original size. Enlarged people had greater strength and increased reach, but less dexterity. Enlarged weapons did more damage, but projectiles or thrown weapons reverted to original size, doing normal damage (possibly enhanced by the double-size weapon that fired it or the strength of the arm that threw it). This version of the spell had a range of 25 ft (7.6 m) and a duration of 1 minute for first-level casters. Range increased 5 ft (1.5 m) and duration increase by 1 minute for every two experience levels the caster had obtained.

The alteration versions of this spell were called enlarge and worked on any single creature or symbiotic or communal entity (like an ant colony) or one object that did not exceed 10 ft3 (0.283 m3) in volume per level of the caster.
