Other new goodies include six new prestige classes, 16 new creatures, over 40 new spells, over 50 new feats, new weapon types, new voice sets, new music tracks, and a new item-crafting sytem [sic]. As good as Shadows of Undrentide was, the additions to Hordes of the Underdark look even sweeter. For several reasons, people love playing and reading about all things drow. This expansion pack attempts to offer a thrilling Underdark adventure and allow module makers to craft their own dark-elf tales.
