skeletron prime is easy for me the problem was defeating by sunrise but i DID IT
YesFor me, it's the Destroyer, but I haven't really fought it in a while. I don't use many of the meta early hardmode weapons, so I can't really cheese him.
Skele prime is kinda challenging, but it's kind of a "you can beat this boss or you can't" boss, your strategy doesn't affect the fight, just your DPS.
The Twins is the easiest for me, I tend to focus on vertical movement and it works out great.
