Blood Moon

You can tell a Blood Moon is out when the sky turns red. There is something about it that causes monsters to swarm.

The Guide

A Blood Moon is a common, randomly occurring event that takes place over the course of an entire night. It causes several hazards for its duration: Enemy spawns increase, even near your Home and NPCs (where enemies do not normally spawn), Zombies become able to open Doors, and Bunnies, Penguins, and Goldfish transform into dangerous enemies, along with other effects (see below). Blood Moons are signaled by the message "The Blood Moon is rising..." in the lower left corner of the screen, and the moon, sky, water, and rain will appear red for their duration.

A Blood Moon will only occur if at least one player in the world has over 120 life, and only on nights when a moon is present (any night except a new moon). Given those criteria, a Blood Moon has a 1 in 9 chance (11.11%) of occurring. Without taking the current moon into consideration, there is an overall chance of approximately 1 in 10 (1/9 * 7/8 = 7/72, or 9.72%).

Effects[edit | edit source]

Enemies[edit | edit source]

  • The spawn rate of monsters on the surface increases, Dripplers Pc only.png, Blood Zombies Pc only.png, The Groom, and The Bride Pc only.png have a chance to spawn. Enemies not only spawn faster, but more are spawned than can normally exist on-screen at once. This works no matter the environment, so Corruption enemies can also swarm even more than they normally would, for example.
  • Enemies can even spawn near NPCs and their houses, whereas those usually suppress enemy spawns. Player-placed walls are not necessarily safe during this event.
  • Zombies and their counterparts can open doors.

Sold items[edit | edit source]

Other effects[edit | edit source]

  • Deathweed blooms. Blood moons are the only time you can harvest Deathweed Seeds from Deathweed (other than during a full moon, as of 1.3).
  • Most NPCs have their own unique lines commenting on the event. Female NPCs act annoyed or rude (except for the Party Girl).
  • Water will turn a blood red color in all biomes except for the Ocean. If it is raining, the rain drops will also appear red.
  • The screen will be tinted red.

Notes[edit | edit source]

  • The Blood Moon's effects on monster spawn rates stack with that of the Water Candle and Battle Potion.
  • Whether or not a Blood Moon will occur is determined at dusk each night.
  • Every nightfall has an equal chance of being a Blood Moon, and does not change if the previous night was a Blood Moon. It is possible to have four or more Blood Moons in a row and, conversely, a Blood Moon will not necessarily occur even over the course of many in-game weeks.
  • In a multiplayer game, using the time adjustment server commands (dawn, noon, dusk, midnight) do not trigger the Blood Moon check, and so using "dusk" repeatedly does not force a Blood Moon to occur.
  • Water in an Ocean Biome will not turn red even though all other water in Biomes will.
  • If a player chooses to, they can cancel a Blood Moon by summoning the Pumpkin Moon or Frost Moon, exiting the game, and re-entering the same world. Most players would not do this, as early players would not have access to those event summoning items, and end-game players would not want to waste a Naughty Present or Pumpkin Moon Medallion.
  • A Blood Moon can happen in the middle of a Pirate Invasion. The event will still go on until it ends, then the Blood Moon starts.

Tips[edit | edit source]

For more elaborate strategies on defeating Blood Moon, including Weapon and Arena recommendations, see Guide:Defending against events.

  • A Blood Moon only affects the surface. Players can avoid it entirely by staying underground.
  • During a blood moon in hardmode, every enemy has a 0.1% chance of dropping the KO Cannon.

Trivia[edit | edit source]

  • One of the "Seven Signs of the Apocalypse" in the Bible states, "...on the 6th sign the moon will arise, showing the color of blood, bringing with it the demons that prowled the Earth, but were sealed away. Then they will feast on those who doubted...".
  • In real life, the Moon appears red during lunar eclipses, and is sometimes referred to as a "Blood Moon". As sunlight passes into the shadow through the atmosphere, the Moon is given a red/orange color due to the amount of air the light passes through. It is the same phenomenon that gives sunsets and sunrises such colors. As such, it isn't a sign of impending doom, and is simply a rare natural phenomena.
  • During a Blood Moon, most female NPCs use more irritable or aggressive dialogue than normal. This may be a tongue-in-cheek reference to female menstruation, a cyclic discharge of blood which can cause emotional disturbances and was once believed to be associated with lunar cycles.
  • When a real Blood Moon occurred on April 14, 2014, a warning was jokingly announced on the official Terraria forums.[1]
