I would suggest to get Molten armor fulls, this makes it easier to survive the fight, and the HM. You can also change all your accessories to Guarding/Warding.

Night's Edge is a great weapon to clear out the initial tentacles that are clinged to the Wall. I suggest you get that. (Molten Greatsword is good too, maybe Blade of Grass)

Do a long bridge from wooden platforms, about 1000 blocks wide to one way. This makes it easy to dodge the lasers.

Get rocket boots/spectre boots. Easy maneuver ususally makes a big difference on boss fights.

Get Phoenix Blaster. This is not required, but helps a bunch.

Drink buff pots. If you are unsure, use buff pots. Iron skin is helpful, and so is gravitation.

That should be all. Hope it helps!
