If you take this product's name as an indication that you'll get a list of 100 possible discoveries for your fantasy RPG, think again; you'll actually get 600 possible discoveries, since the product presents six different tables of 100 discoveries each. The tables pertain to various locations typical in a fantasy game: castle, dock, temple, swamp, park, and mountain. I found the various entries to spark my imagination, and I expect to drop some of these events into my own games from time to time. Unfortunately, the content is marred by enough occurrences of poor grammar, awkward style, or outright errors that the editors should have caught before the product went public that an otherwise four-star product gets only three.
