Some quests give extra slots for your inventory (bag) as a reward. Below is a list I found of all those quests.

I was leaning towards playing a Sorceressfor my main character in BDO but then I learned it is the hardest class to play. So I am pretty decided on playing a Tamer now. It is said to be the easiest class to play and it looks like a lot of fun. You get a pet and you even can ride it once your level is high enough.
With my pre-order, I am getting some guest passes. The pass allows someone to create an account for Black Desert Online, download the game and play it for free for a week to see if they like it. If you seriously considering to buy and play the game but are still in doubt: feel free to give me a shout if you would like one of the guest passes.
