Calamity Murasama is much better than the regular terraria Muramasa

But is it used in the zenith?

It doesn't need to be used in the zenith, the Murasama deals a max of 10,000+ damage
The Zenith can deal 5000~ damage

It's like the zenith but stronger

And easier to get

Sadly it is a mod

Well... if you name your character Samuel Rodriguez or Jetstream sam and then go get it from the underworld then it's easier to get than Zenith

it's easier to get either way

(or nights edge depending on how you look at it)

I never new the Muramasa existed until I decided to get the Terra Blade. I eventually used it for the Zenith, which was an interesting quest to get because me and my friend were both trying to get one in the same world.

20+ damage vs 10000+ damage

MEMORIES BROK-

Oh so true
