I've never used that myself, that explains it. So it's insanely OP? I'm guessing he got a visceral attack with it, but still, 75% of Father G's HP gone at once is ridiculous. We -skipped- the second and third phases.
I just got past BSB and got Ludwig's Holy Sword. It's doing a lot less damage than the Saw Spear, even on humanoids, but I take it that'll get better with weapon levels (WTB Twin Blood Stone Shards) and Arcane levels. I'm doing Hemwick Lane next and I'll try to get everything there / defeat the witches before I go after Vicar.
When does an "arcane run" start to feel like an arcane run? Like when is the first Hunter Tool? So far it's been just like a normal run, except with me putting points into Arcane at the cost of my regular stats, making everything harder. Like others have said, it's really too bad there isn't an arcane spell earlier in the game. I'm using molotovs and flamesprayer, at least, but those are very limited in overall use.
