Aight, don't own the game so I have questions for Souls veterans:
How varied can a character build be?
In general, whats the best build when it comes to attributes?
What's the most OP weapon thus far when fully upgraded?
1) character builds are basically the same across the board in Bloodborne and nothing at all like it is in the other Souls games. Theres next to no variance here. Sure you can plunk points into shit like arcane or bloodtinge but in the end everyone is the same quick character that swings a handful of the same weapons.
2) I don't know about the best but it seems like most of the weapons outside of lone or maybe two of them are governed by strength. IMO strength, vitality, endurance, and skill (in that order) play the biggest role. I'm still not sure just what the fuck bloodtinge is good for and arcane is somewhat useful on certain weapons but largely unnecessary in the end.
3) my weapon of choice is Ludwig's Holy Blade. I'm not sure if it does the most damage but it does a hell of a lot, the moveset is pretty handy, it's relatively quick when compared to the Kirkhammer, and the two handed charged thrust can be devastating. I also really like the Tonitrus with its electrical damage.
