Im poor and cant afford good gear or anything for dex charms/armors.
i got a lvl 42 barb and ive put points here and there in to my dex and im at like 72 and was thinking an extra 15 dex wold not be bad. cuz i hardly ever crit.

Your gear and stats aren't really bad to be honest. You have a good balance of Str and Dex you could try increasing it to ~100 and stat the rest str. You just gotta grind those higher
levels out and hope you can hop in some catas

Good luck and if you have any further questions, let me know!

i like to solo tho and i never crit often so i dont hit high and always get owned and i like to well and its hard at thease lvls now unlike at my lower lvls =/

Monsters do get quite a bit tougher at higher levels because your gear becomes less and less perfect for the level. But, you will find it extremely difficult trying to well w/o a heal charm at higher levels just an fyi

I'd honestly recommend going with a fighter, as it's much easier to hit a decent amount of dex early on.

Also, like Tyler said, you'll need some sort of heal charm to be successful welling at high levels. You'd want to either play a hybrid character (hard-statted int on a melee char to help with healing), or a caster.

Let me know if you have any further questions ofc.
