Then I'm even worse.
The game DOES have a pretty big learning curve. I doubt you're the only one getting stuck in places like that.
From what I understand, it's not uncommon for a new player to get a certain distance in, sort of hit a wall, and realize that their character build just isn't working. Which is when it's time to start a new one, hopefully improving on the previous concepts. And starting totally new characters sounds like something that's done FREQUENTLY in this game for a bunch of reasons. Probably why levelling up is so quick.
I ended up watching a few tutorial videos myself very recently (and also installing a loot filter designed to help new players). Particularly for when it came to stuff like the economy... that currency stuff is more than a bit confusing at first. Such a unique mechanic though.
Currently I'm using a witch who specializes in summoning exploding skeletons for some reason. Cant go wrong with exploding skeletons. Well, if this were Minecraft then you could go wrong with them, it'd mean some sort of hideous skeleton/Creeper combo....
