In the Dungeons & Dragons game, drow characters have the following adjustments to their ability scores: +2 Intelligence, +2 Charisma, +2 Dexterity, -2 Constitution. Drow males are commonly wizards or fighters. Females are almost always clerics.
Drow hate elves, but wage war with other terran and subterranean races, such as mindflayers (or Illithids) and kuo-toa for spoils and territory. Their society is matriarchal, with priestesses of Lolth in the highest seats of powers. Males are either enslaved or (rarely) respected if they are powerful enchanters, but never allowed to rule.
Drow were designed for the worlds of Oerth and Abeir-Toril (Forgotten Realms), but they may be found in many other published and GM-created game settings.
