Phantoms are flying undead hostile mobs that spawn in the night sky when the player has not laid in a bed or died for three or more in-game days. They attack by diving at the player from the sky to bite them. Phantoms attempt to spawn every 1–2 minutes. They spawn only if it is night or a thunderstorm is happening, the player is above sea level (y=64) with sky access, and the local difficulty is greater than a randomly chosen value between 0.0 and 3.0. The chance of a successful spawn is x−72000
