Hey Terrarians! When exploring underground, always carry glowsticks or torches to light up dark areas. This will help you spot hidden ores and avoid falling into pits. Also, make sure to build a hellevator early on – a vertical shaft straight down to the underworld. It’s a quick way to access different layers of the map. Lastly, don’t forget to bring a Magic Mirror or Recall Potion to quickly teleport back home when you’re deep in the caves. Happy exploring!
