Brain of Cthulhu [Terraria][Legendary Mode][Ranger Class]
Beat Brain of Cthulhu using the Ranger (Archer + Gunner) class in Master Mode on the Zenith (Get Fixxed Boi) seed, also known as, Legendary Mode (version 1.4.4.6). You can pick either Brain of Cthulhu (Crimson) or Eater of Worlds (Corruption), but one of them must be beaten first to upgrade your Pickaxe, so you can venture further into the Underworld to mine its stone and create Molten armor and weapons to advance. I find the Brain a little easier than the Eater, so I tackled it first.
