I am trying to collect words of power and I was directed to find one in the ruins of Ragnvald. This is by far, the toughest dungeon I have attempted to clear.
It is harder than Hag's End was, it was harder than Labyrinthian, this one takes the cake. All dungeons before this one were easy/moderate in difficulty. This bad boy is impossible.
I knew I was in trouble when the "basic" enemy found in the ruins were Draugr Wights, I am level 10, so when I fight 2-3 of them, I am chugging health pots. The ruins then have 2 mini bosses that were a fight to the death for me.
After each I had to leave the ruins and resupply... something I have never had to do before. My companion was only remotely useful, when she tanked a few hits, etc.
I slugged through it though, determined to get that word of power. I am now at the final obstacle, the dungeon boss. It is a powerful lich, almost identical to the one I fought in Labyrinthian on another file. He does tremendous damage, two bolts of lightning and I am dead. He has a whopping amount of health, we slug away at him and we take a quarter of his health.
This is the most epic enemy I am grateful to fight. Realizing my inability to win a standoff, I change my strategy to incorporate the dungeon in creative ways. There are spots of fuel on the ground which I did not use earlier and a path of swinging blades that are still working. My plan was to wake the lich up, whomp him as much as I can while he is finishing his "hey guys, I am leaving my coffin now" animation, fall back to the fuel, try to poke him with whatever limited damage I have (warrior class), ignite him while on the fuel and then duke it out, using the swinging blades as a retreat point.
I thought it sounded like a decent plan, so I execute. I get him down to about half health with the fuel and my attacks before I realize that he is REALLY strong. I chug my last pots and barely make it to the retreat point alive. I have a few useful words of power, such as ethereal movement, so the blades won't hurt me, so I can keep them moving forever.
The lich camps outside of the swinging blades, hoping I will pop out and he will blast me with the final lightning bolt, but I am too cautious and he does not get a clear shot. He gets greedy and decides that a few blades won't hurt him, so he runs right into them, they tear him up. For how much damage, I don't know, wasn't close enough to tell. He falls back though realizing he cannot get to me.
So now I've been fighting this guy for maybe... 20-25 minutes. Then something awesome happens.
When he gets below 40% health, the game freezes. Always. This is not an isolated incident, it happens every time. Every time I retry killing him, it freezes. It is like his ultimate weapon. When he knows I got him, he freezes Skyrim.
I've never fought an opponent who was literally impossible to kill.
Sorry for the long story, I'm sad.
