TIP NUMBAH 1: You will die, so many times. Don't buy this game expecting to beat this game in a few hours. This game takes time. Lots of practice. You need to look up guides sometimes. This isn't one of those games you can take a break from either. You will get rusty, and therefore, suck at the game.
TIP NUMBAH 2: Parry. Parry all the time. You can't parry all enemies. Most small enemies you can. When you parry immediately push light attack. This creates a riposte that does critical damage. It is very useful and can save your life, but sometimes it can end it.
TIP NUMBAH 3: Use rolls. Definitely make sure you have a fast roll also. You will fail rolling if you have a 'medium' or 'fat' roll. Eventually if your equip load is to high you won't be able to roll at all.
TIP NUMBAH 4: Make multiple characters. This is useful because when you beat the game several times you start to be a master at it, all the locations of chests and rings. The game never gets boring especially since the game encourages multiple replays.
TIP NUMBAH 5: Last but not least, use builds. By builds I mean that have a certain weapon you want to use the whole game. Such as the Black Knight Sword. This weapon is a strength weapon. So you want to put your level points into strength. You want to put them in Endurance and Vitality also, but strength is your main weapon level point location.
These are the top tips I could come up with! Good luck! Don't break your console/pc because you are bad at this game! IT TAKES TIME AND PATIENCE!
GAP and DTM

These are the games in the Souls series. Like I said, Bloodborne isn't really a game in the souls series, but then again it is.
