Doug isn't a normal magician. Dwalinor is the pure mage expert in the Warriors (from what I gather) also I'm sure the Warriors would at least call on a few friends to help with that situation that would double check Dwalinor's work. Doug just played a song (that I can't recall at the moment). While Doug might know magical theory but knowing only a few words in a language (and ones seldom used at that) doesn't make someone literate and able to understand that language. From what I've gathered about Warrior's World a good portion of those magic texts have been translated into English or a more widely used language.
