The game is too hard. I can't kill Count Geonor ( 30+ trying )

I play as a Sorceress.
The situation is just f***ed up. I've completed the castle location 30+ times. But I can't kill the final boss. F***ing Count Geonor kills me all the time. I've already leveled up to level 20, and all my magic skills are level 5. All my items id gold color.

I just don't understand what I'm doing wrong and why the hell I can't enjoy the game and have to fuck around with completing the same location.

Make a f***ing change in difficulty level for noobs like me. I want to play, not jerk off to the same location.

You see, the problem doesn't lie in the game, but in you. If you're dying, it's most likely because you don't understand how to create a working character build. Yellow items don't give an advantage on their own if they have poorly rolled options. A well-rolled blue item can give much more than a poorly rolled yellow item. If you can't create a working build yourself, you can look up how to build the class you're playing on YouTube. You have a problem at the very beginning of the game, and it gets even harder later on. Maybe you're used to games being simplified (like what happened with the Diablo series) where you don't have to think intensely about how to build your character. Look for guides on YouTube, as they will help you understand what to pay attention to. In the case of this boss, also check how much cold resistance you have. Do the same in the second act; for the final boss, check how much lightning resistance you have. Hundreds of thousands of people enjoy the game, there's no need to simplify it, you just need to take on the challenge, improve your build, and practice dodging.
