It's better to get the adamantite armor together with the assault rifle (dropped from the wall of flesh) and use the 'Crystal bullets'. Also get some greater healing potions and make a few large platforms above each other, because the destroyer is weak on platforms. Or you can always start a server on hamachi and ask a friend to help you.
