This dungeon is a very long one. Sometimes you will be faced with a large group of enemies that are very hard to dispatch and someties you will run into them one by one.
Often times if you make sure that you sneak around a fair bit you can surprise Draugr that are lying in their death beds and kill a couple of them before they can even react to noticing you and a 4 on 1 situation suddenly becomes a 2 on 1 situation which is much easier to handle.
When you are in a fight with 4 or 5 enemies you want to make sure that you keep checking your health. I have noticed that often times when I am just fighting I get surprised by falling over dead not noticing how fast my health was dropping.
In a group situation you will want to try and minimize the amount of enemies that can hit you at once. A good way of ensuring this is to maneuver in such a way that one of your enemies is behind another which means that the cut off enemy then has to flank. If you keep moving around to the side and attack the group where it only has one opponent sticking out often times you can avoid being hit and surrounded by a lot of enemies.
There is a puzzle at the end of this quest. You can find the solution in part three which should be up as soon as this is up as well (check on my channel). What you have to do is insert the wooden square that you were given earlier into the leftmost stand. Then, from left to right, push the first button to the right until the next button to the left lights up blue. Keep doing this until you reach the last of the four buttons which is on the far right past the center console. Once you push that button once the elder scroll will come out of the crystal egg which has been lowered in the middle of the big circle in front of you. This is practically the end of the quest, all you have to do now is bring the elder scroll to the throat of the world and read it out in the place that is shimmering and has snow flying around it weirdly.
