On Skyrim the Breten is the class. He wasn't part of a guild. He more or less went about randomly doing things. He did it with an elfin bow. What he did he got close enough to the giant to shoot an elfin bow at him and then he would run until the giant quit pursuing him, and then he attacked him with the bow. Until he got in the tower where your suppose to meet Yarl's dragon. The dragon wasn't there. I on the other hand ran across a giant at level 7 today. I had a wood elf with fine Imperial equipment. My bow was a regular Nordic with Iron arrows. I did it behind a rock not in a castle. I was playing the storyline, so I only did it only twice. I also wasn't part of a guild. My perks is in sneaking, one handed combat, and heavy armor. I don't know his perks.
