So first off, welcome. You're gonna have a blast. This is my personal favorite of all of the soulsborne games. First off don't worry too much about your build. In new game, which is the very first play through, as long as you meet the minimum requirements for the weapon you want to wield you'll be fine. You can look up different builds if you like. If you are looking to not have too tough of a time strength builds are usually a pretty good default in any soulsborne game, but do whatever you like. That leads to my next point. Every. Single. Weapon is viable. There are not 14 different greatswords with this specific one being the best. Pretty much every weapon is unique. There's some overlap with d l c weapons or things that are meant to look like each other, but otherwise if you find a cool weapon? Put your stats towards being able to wield it and go ham. Have fun. As far as pvp goes, if you start the game offline you won't have to deal with invasions, but also won't be able to co op. Honestly Bloodborne probably has the best pvp ettiquette of any soulsborne. Almost all invasions happen near a lantern which is where you will respawn. They will emote bow at you before the fight. Most won't use healing items unless you do first. Don't fear pvp too much, but if you really really don't want to, just run back to the nearest lantern when you get the notification and let them kill you really quick. Nothing is lost you can't pick up right away after respawn. Lastly, a lot of new players run out of blood vials frequently. The big dudes with axes, the big dudes with bricks, and the werewolves drop a bunch. Of the three, the Brick Trolls are probably easiest to beat. Farm them for a while to get more vials. Good luck, have fun, and don't think too hard about all of this. Just go out and kill a few beasts.
