I defeated (SPOILER)Sif and the Four Kings on the first tries. My character has a sizable amount of vitality at this point so I was just able to throw on Havel's armor and kind of tank through both fights. Not the most graceful victory, but it worked. Now I'm onto (SPOILER)Gwyn. He kicked my ass the first few times we tangled and then I decided it was time for bed. I'm eager to try my hand at it again.
