Physique (3rd Edition)
Slightly shorter than the average human, elves are also noticeably more slender and graceful (this is reflected in a bonus to Dexterity and a penalty to Constitution), handsome and beautiful averaging between 4½ to 5½ feet and 95 to 135 pounds. Males are slightly more muscular on average, there is little difference in height between the sexes, and neither sex grows facial, nor body hair. Their features in general may be described as more angular and defined, including long, pointed ears and wide, almond-shaped eyes. Most elves have fair skin and dark hair, though this is no more true of all elves than it is of humans. They have a reputation for careful grooming, more so than perhaps any other race. This frequently extends to their clothing, which is luxurious and well-kept, though not to the point of impracticality.
Elves do not sleep as most other creatures do, instead falling into a four-hour restful trance. Consequently, elves are unaffected by sleep-inducing spells and effects, and are able to remain active far longer than other races.
Elves also do not age as other creatures; their physical appearances remain constant from achieving physical maturity to death. Elves do grow physically weaker and mentally stronger as they grow older, and accumulate a "glow" from the strength of their souls as they age.
