So I used to play with 10 vit and rest to str barb build, but I'd like to test something like dex/str build so I can crit more. So from your selfexperience, what kind of build do you suggest?

i find 45~60 is a good min range for basic defensive purpose depending on how much you wanna spend

Well, you could try out a club barb and maybe get around 80 dexterity and pump the rest into strength.
You might also want to play with a fighter if you're looking to do a bit more damgae.

ah I totally forgot about the weapon set I'm using. I like axes, so I used them in all the last climbs.
