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


"The Blood Moon is rising..."
A Blood Moon is a common randomly occurring event that takes place over the course of an entire night (7:30 p.m-4:30 a.m.) It causes several hazards for its duration: Enemy spawns increase, even near the player's 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 the duration of the event. A reddish-pink filter will also be present in all above-ground areas.

A Blood Moon will only occur if at least one player in the world has at least 120 life (six hearts), 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.

Other effects[edit | edit source]

  • Deathweed blooms. Blood moons (and Full Moons on Desktop version Desktop and Console version Console) are the only times you can harvest Deathweed Seeds from Deathweed.
  • Most NPCs have their own unique lines commenting on the event. All female NPCs except for the Party Girl act annoyed or rude.
  • As said before, water will turn red, including Rain. Desktop VersionConsole Version A red filter will be applied to the screen as well, shifting the colors of all entities and light towards red and purple shades. This will also affect the projectile colors of many weapons.

Notes[edit | edit source]

  • The Blood Moon's effects on enemy 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) will 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. However, the blue water is still affected by the red shader, giving it a purple color.
  • If a player chooses to, they can cancel a Blood Moon by summoning the Pumpkin Moon or Frost Moon.
  • A Blood Moon can happen in the middle of a Pirate Invasion. The invasion will still go on until it ends, then the Blood Moon starts. A Blood Moon can also occur during Slime Rain.
  • Blood Moons occur more often than Solar Eclipses, as Solar Eclipses have a 5% (1/20) chance to happen each day (when the criteria are met).
  • There is an whole new soundtrack to the game while a Blood Moon is active. The soundtrack is spooky and definitely adds a horror element to the event.

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 1 in 1000 (0.1%) chance of dropping the KO Cannon.
  • Simply placing a block in front of a door will prevent zombies being able to open the door.
  • If you see the notification that a Blood Moon is rising, get underground as quickly as possible. Going indoors will not save you. Neither will standing around outside. The Blood Moon gives enemies dangerous abilities, such as the ability to open doors or the ability to spawn within player-placed walls.
  • Although the Blood Moon is typically treated as a deadly event, it is possible to enjoy the event. To prepare, find some Life Crystals and increase your health as much as possible. Then craft or buy (or find) a weapon with fast speed, good knockback, and good strength. Then, when the Blood Moon rises, go on a monster killing spree. Since there are new enemies during a Blood Moon, try launching a hunt for these new enemies.

Trivia[edit | edit source]

  • 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. This is the same phenomenon that gives sunsets and sunrises such colors.
  • When a real Blood Moon occurred on April 14, 2014, a warning was jokingly announced on the official Terraria forums.[1]
  • During a Blood Moon, most female NPCs use more irritable or aggressive dialogue than normal. This is a reference to the fact that some women in real life become irritable or aggressive due to premenstrual syndrome, as both the menstrual cycle and the Moon cycle occur approximately every 28 days.

History[edit | edit source]

  • Desktop 1.1: The chance of a Blood Moon was decreased to 1/9 from its previous chance of 1/7.
