Time
Time is the material that our world and Terraria revolve around, At night evil monsters will come out of their dens (They just spawn if you don't like roleplaying)Monsters spawn at 8:00 PM (Get a Watch to know when its almost time) or look at the sky to see the time, the clouds will start to get pink-ish when it turns 3:00-3:30 PM, Then when it gets about 5:00 PM the sky start to dim down, at about 7:00-8:00 PM monsters start to spawn and you must survive the night and wait out till day, at 4:00 - 4:30 AM the monster will retreat, if you want their loot then hurry and kill them because as soon as they run off your screen they disapear.
