If you use Dragon Aspect and look under your Active Effects you can see what it does, I only have the 1st word. That gives; +25 armor rating, and power attacks do 25% more damage for 300 seconds. If you have 3 words try it out yourself and check, i'm guessing it won't add any more stat + or %, except for the +/% you get on the first word.
