I was finally able to kill the Blue Dragon in Demon's Souls. It was good to take a break from the game and come back full force again with it (this video was very helpful too).
I also did the online event of the Old Monk of being the Black Phantom; And I have to say that it feels weird being the main boss... the dude did a good fight and it was pretty intense and also I managed to get the Monk's Head Collar that I needed to kill the Blue Dragon in the process.
It didn't feel good killing the player though, maybe is because this game is so damn challenging and demanding that you really can feel sorry for the other guy that lose against you. But then again, those are the rules of the game.
But yeah, I'm pretty close again to finish this. Can't wait for my third playthrough!
