In Bleak Falls Barrow, it's pretty rough in there as well, it's rough everywhere(I only got through it because of Faendel, go wood elves!) The wounded frostbite spider killed me in one hit, with it's poison. Faendel, however, took so many hits I thought he was an inch away from death, turns out, the tens of hits that he took didn't do anything. If it wasn't for him, I would've never gotten through it.
Interestingly enough, dragons, are finally a challenge. The first dragon fight that everyone goes through, was hard and long. My first attempt at fighting it, I was like " I'm going to be a boss and fight it head on!" Don't do that, ever. It landed, and I died. The second time around I was a bit smarter. I decided to stay at the top of the tower and try to pepper it with arrows. It picked me up, mid-air, and I died, in mid-air. Third time's the charm, right? It is. After having a strategy of going down the steps whenever the dragon flew over, or tried to rain it's merciless fire upon me, it took 20 minutes and hundreds of arrows, to make it crash land on the ground(I always love seeing that happen.) I went down there with a sword and shield in hand, and it took 5 minutes to kill the beast like that, but it was so worth the trouble, it felt good to finally kill a dragon again.
After all this, I decided to just mess around a little with some giants, I went up slashed a giant's toe. It took a step forward, and I collapsed dead on the ground. Then the auto-save came along, and I respawned at Whiterun's City Gate. There were three hired thugs. I thought "Dude, I just killed a dragon, you don't have a THING on me!" Once again, I was wrong. They murdered me and Faendel. The second time around, I tried to run, they caught up to me, and bashed the back of my head in with a war hammer. Once again, third time's the charm. I ran, with them still in pursuit, thinking I had lost Faendel, to the giant's camp. They weren't pleased to see me, or my guests of honor. At first the giants were only after me, and I ran away like a little baby scared to death. But the giants finally took the offensive towards the leader of the thugs. He actually put up a fight, against two giants. It scared the mess out of me. No wonder I couldn't kill him. I thought the giants had taken care of the other two, but they decided to hide behind some rocks and ambush me. Which, didn't end well because they were smashed to bits by the giants in hot pursuit behind me. Still, the giants were after me, and I'm thinking, "Oh, the 10 Whiterun guards at the city's gate would help tremendously." So I brought the giants into the gate of Whiterun. They attacked citizens, the Kajhiit traders, everyone, except the guards. The guards, just stood there doing nothing! I facepalmed and went inside.
That is where the story ends for me right now, level 12, in Whiterun. It is definantly hard. But, it is a lot of fun! Thank you, Bethesda.
