Oh dear god then let us go give all bats a kill, because pixies are glowing assholes with wings. At least i can one-shot hellbats.
But then there will be no greater healing potions, rainbow rods, holy water, holy arrows and fairy bells!
I just fought the WoF to see what it's like.
I need to study the lasers it shoots.
Actually, if you have full Molten Armor, one or two Ironskin Potion, one or two Regeneration Potions (those are
really useful) and a good supply of Healing Potions, you should be able to just tank it. Although I got dangerously close to death twice during my fight with it. If you're pre-Hardmode, you don't really need too many accessories. Cloud in a Balloon, Specter Boots, Mana Flower (if you use the Demon Scythe which is really good, but really rare) and Obsidian Shield are the ones I used. I also had a Golden Horseshoe, but you don't need that in the fight, so replacing it with a Band of Regeneration might be a good idea.
You do wanna avoid the Hungries, though. Those do
ridiculous damage, so kill them fast. I used the Star Cannon for most of the fight, but using the Demon Scythe should work great, too, especially with the Mana Flower since you'll automatically use a Mana Potion when you run out of mana and those don't give you potion sickness.
