Yaaay congrats! When you get tizona, megashark and titan armour, you will kill that thing in 6 seconds flat! It's so good for money! :D Try and kill the destroyer next, and kill it in daytime so that less mobs will be around. If you can, get a goblin army and try and get a harpoon or boxing glove. Very good against the destroyer, but a minishark will work just as well C:
