Soo
first my favorite profession so far is locksmith at first i thought it was healer but its too hard to get exp and it cost alot
i chose locksmith because by just level up you can get +1 from chests just have highest locksmith each level and its not that hard to gain because you can get chest each level so you can basically open them for free
at first you wil think damn at higher levels its very expensive to buy lockpicks but sometimes you can open like 5,10 maybe even 20 chest and that not alot for that amount
If there was a 4th proffesion it would make something to do with hunting like raising +1 with monster kills or monster related stuff and you would get some bonuss for killig em i dunno im not a developer but that would be fun
but if i can take any of 3rd proff for 4th it would definetly would be exe cuz it good in higher levels
