Zargerth

I was just playing Bloodborne, finally reached Forbidden Woods (yeah, I'm not very good). Before that, however, I went and beat Djura's ass- screw you and your gatling gun!

I still insist that thus far the most difficult boss of the game is Father Gascoigne. He is also the first boss (you can kill Cleric Beast first, but that's optional). I died like 20 times before finally beating him.
