I will say that Night’s Edge is pretty helpful against bats. Early hardmode, bats can be a pain in the
to deal with with their small hitbox and erratic movement, and Night’s Edge, as a large broadsword with autoswing, is pretty effective at keeping them off. How much that’s worth is up for debate, but in my last melee run I did hold on to it for a little while just for the sake of keeping early hardmode bats off of me. More effective than a gun or many other weapons in that case, at least.
Definitely don’t use a broadsword without a projectile against projectile enemies. The closer you are, the harder their projectiles are to dosge, and in expert+ I wish you luck tanking them. If you knock the enemy too far away, they can just start shooting again. Especially ichor stickers, their projectile moves insanely fast and is punishing against tanks.
