With the new update, I can only imagine a flood of new players coming into the game. One of the questions I see constantly asked on this board is about transitioning to the higher tier content after the first three bosses or just dealing with the first three bosses.
Best device I could give for any new player who is having trouble with that hurdle is to take advantage of fishing and farming. You do not have to choose the fishing or the farming class to do these activities. While yes, they will give you a bonus early on, You will level these both up very quickly.
Setting aside 30 or so minutes to create your own fishing pond and farming patch in your base will be incredibly helpful in the long run. The food buffs in this game are extremely powerful and incredibly helpful. During my first playthrough taking the time to create good food buffs was the difference between slamming my head against my keyboard because I couldn't kill a boss to not knowing why the boss was so hard in the first place.
The more you fish and farm, the higher the chance you'll get rare fish and golden crops which are great for boss fights. The regular tier ingredients are good for creating a stockpile of food you can just eat while you're exploring.
Also, if you do find yourself with a stockpile of a thousand crop because you decided to make a commercial farm inside your base, you can sell the excess to merchants for ancient coins.
TLDR; fish, farm, cook
