This module features 67 encounter areas, plus new monsters such as the Jousting Wasp and Glutinous Gunge, as well as known monsters like the Talon Goblin and Cadaver Spiders.
Wait! You don’t know what the Jousting Wasp and Glutinous Gunge are???
Then you will have to download New Materials Volume II, which features 30+ new monsters, new magic items, new mundane items, and new information about currencies of the realms!
Check it out, it's all free (and good).
