If you have a long platform a little ways from the ground, it will help alot, as you can leave a small 2 block hole in it and the Destroyer should spend some time below you burrowing before he decides to come up at you. you can blast him with your strongest gun through the hole if you stand very close to the edge of the hole. this may also give you the chance to reagin health. this is the tactic i have employed and he was very easy, just has massive hp and the little laser balls get annoying
