One strategy, Two variations. Depends on How cheesy you want to get. First the basic strat. You want to use a piercing weapon (one that doesn't automatically come back when it hits something) so you get multiple hits per swing, Dao of Pao is by far the best. Next you want stand on its body and throw the flail out so it travels along the body. The body does much less damage than the lasers. You also want that cross necklace. Use potions as needed, and also kill the probes for extra hearts. To add cheese, make an arena floor out of meteorite or hellstone and don't wear any obsidian items. That way you are constantly damaged by the floor and can never be hit by anything else (in full adamantite it only does 1 damage per tick). This is exploiting a game mechanic in a way not intended though, some might feel guilt over it.
