make a tower with the edges of wood, empty, with some platforms around so u can move freely inside it. This is an Arena. Summon the boss and get ready when he comes up/down to easyly avoid him. Be prepared to kill the minions and recover health. Try to have enough defense so that lasers dont threaten u too much. Rest should be easy, as the Destroyer doesnt split up like The EoW ;)
