Quick tips

  • Build a house for the Guide before the first night and keep him close: he shows you every recipe.
  • Collect Life Crystals underground early; each adds 20 maximum health.
  • Build a long arena with platforms and campfires before every boss fight.
  • Wear armor that matches your class and use potions: Ironskin, Regeneration and Swiftness help in every fight.
  • Save before beating the Wall of Flesh: Hardmode changes the whole world.
