Well, there’s no real set order in which you should face the bosses. But the order I did it my first playthrough was:
- King Slime
- Eye of Cthulhu
- Brain of Cthulhu/Eater of Worlds
- Queen Bee
- Wall of Flesh
When entering hardmode, I’d recommend beating each of the mechanical bosses multiple times for the drops. The order I did:
- The Destroyer
- The Twins
- Skeletron Prime
After the mechanical bosses, it’s pretty straightforward.
- Duke Fishron
And after Duke Fishron, you have the event battles.
Do Pumpkin Moon first, and save the Frost Moon for last.
Feel free to reply or PM me with questions on how to prepare for or do any of the boss battles.
