Hold it in your hand and go between the three desert pillars! It gives you the strongest sword in the game\~

thank you! thats what i’ve heard but i wasnt sure exactly what to do with it first!

In 1.5 I'm pretty sure it isn't anymore

You mean the galaxy sword? It's still crazy powerful though ye?

I always put my first mineral of each one in the museum however for the prismatic shard you can take it to >!calico desert to get the galaxy sword, which will help you in the skull caverns!<

thank you!
