I just beat that level with the Dragons and the knights at the end. Oh man, what an amazing game this is.
In the last area I saw a message saying "Keep your composure" or something like that (I wasn't playing in English). The first things I see are clearly enemies but they bowed to me and waited so I could fight the big guy. I thought they were going after me after I killed the big knight but they stood still. And there were so many of them through the whole level! I didn't want to fight them since they were so polite so I just kept going until the end. I'll make sure to come back here when I finish the game to fight them and see what happens.
I think I'm almost at the end of the game. I don't want to see any walkthrough to make sure. People in the Dark Souls III thread said that I can wait to go to New Game+ in this one too so after the credits I'll come back to revisit some places (I have like 3 pages in my notebook with notes about some places).
Anyway, I'm rocking a Greatsword +10 for the first time in this series and loving it very much. I also have an Estoc +10 and Short Bow +9 in the other hand, using an upgraded Elite Knight Set because, well, it looks very good. Not using magic of any kind.
Next I'm thinking if I go open the door at the Castle using the king's ring or if I go to some shirines that I saw all over the game (I guess these places are the DLC areas?).
Edit: Just finished the main game!
Second try on the last boss solo if anyone is interested in seeing it. I even tried to kill those things that were cursing me, without results of course. That was easy compared to Dark Souls 1 and 3. Great game. Now the DLC areas.
Edit 2: Seeing the above video againg killing those things actually worked. I was hit so I thought I wasn't supposed to do that lol. It was very fast.
