If you ask me, it's way easier to just hop into a new world and fight one than it would be to farm a rare item and summon the thing this way. Plus, in a new world, you could just keep trying over and over every time you died, but with this, you loose the voodoo doll and have to get a new one with every failure (and odds are, you're going to fail a lot...)
