Hey fellow Terraria adventurers! When exploring underground, always carry a good supply of glowsticks or torches to light up dark areas. This will not only help you see better but also prevent unexpected enemy spawns. Also, make sure to bring along a Grappling Hook for easy maneuvering through caves and grappling onto higher ledges. And don’t forget to create a Hellevator – a straight vertical shaft from the surface to the Underworld – to make traveling up and down much quicker. Happy exploring!
