All your usual defence potions and maybe a space gun if you're planning to stay above lava. Or if you want to go in where there's a lot more hellstone to harvest, craft some obsidian skin potions and gills potions so that you won't get hurt by the lava and can breathe in it. Really important to keep an eye on your potion meters though because they both have different durations so keep your finger on the B key in the last 10 seconds, *especially* for obsidian skin.
