with 4 hearts that will be hard. Don't get hit! 1 Hit from him = instant death also, don't get too far away! He'll use shock arrows and you'll have no chance at winning! Increase your hearts over your max at least 10. You'll be fine. but you'll need to keep eating! Be careful of his fireballs. They'll do decent damage. And you don't NEED to kill him. You can just get the shock arrows in the trees.
