To illustrate this post I wanted a nice image of a Drow with their stylised hand crossbows which is the absolutely iconic drow weaponry. Every image I could find that was useable seemed to be anatomically challenged.
Before I get into the actual game mechanics of the drow weapons I want to say something about their construction. The material of choice being Adamantine, a jet bacl metal allow of Adamantium and other metals. It reputedly has a green sheen when seen in normal light but a purple/white sheen in magical light. Adamantite is very light and very strong, most of the time.
