User blog comment:AnimeStar45/What sword should I get now?/@comment-1250011-20131012210046

Work towards getting a Broken Hero Sword during a Solar Eclipse and upgrade your Night's Edge to the True Night's Edge. I have a Legendary one and it works nicely for any hard mode enemies/bosses I have to take on.

Once you have that, you're a step closer to the Terra Blade, which is a sword I'm working towards as well. ^^

Another drop you could get from the Solar Eclipse would be the Death Sickle, which is another great weapon to use Post-WoF.
