Drow Sign

Drow Sign is a sign-language type tongue which uses hand motions and expressions. It is, as the name suggests, used mainly by the drow elves. Humans and other goodly races often confuse these motions as spell conjurations. It is notoriously difficult for non-elves to master, as they often lack the manual dexterity and slenderness of an elf's hands. Even the incredibly dexterous Artemis Entreri had difficulty getting his hands to enunciate the movements properly and lacked the finesse of a drow even years after learning the language.
