It features cover art by Francis Tsai, and interior art by Steve Ellis, Wayne England, Lars Grant-West, Tomás Giorello, Jackoilrain, William O'Connor, Richard Sardinha, Beth Trott, Francis Tsai, Franz Vohwinkel, Eva Widermann, and James Zhang.^[2]

"New Monsters and NPCs"

Numerous new monsters are presented in Drow of the Underdark, including the deep dragon, trolls, goblins, and draegloth.

Statistics for one monster, the vril, were accidentally left out of the book.^[3]
