A Call Beyond
This tool is so strong it could make your enemies cry. You get it after beating the Celestial Emissary in Upper Cathedral Ward. It takes 40 arcane to use and throws tiny bombs around you that follow you like a bunch of jealous kids.
I used A Call Beyond and my enemies exploded like a bad birthday party.
My arcane was low, but I still used it and got yelled at by the game.
It's like having a bunch of tiny bombs chasing you.
