Words of Power

Learn all three words of a single shout. Shout words are found at Word Walls in dungeons, but you also need a dragon soul to unlock each. The easiest is Unrelenting Force: you get its first word in Bleak Falls Barrow, the second from the Greybeards during The Way of the Voice, and the third from them right after - three words, one shout.
