We have begun migration of most wikis to our new host, Amazon Web Services. All but the top 100 wikis are in read-only mode until the migration is complete. Estimated completion: TBD -- Update: Fri 10/20 11pm UTC - We have encountered some unexpected issues. Our staff is working around the clock to complete this process as quickly as possible. Thank you for your patience.
You can tell a Blood Moon is out when the sky turns red. There is something about it that causes monsters to swarm.
"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, 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%). Though it is not that simple, so do not always rely on the numbers.

Effects[edit | edit source]
Enemies[edit | edit source]
- The spawn rate of enemies on the surface increases. Dripplers , Blood Zombies , The Groom, and The Bride 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.
- Goldfish become Corrupt Goldfish/Crimtane Goldfish, and Bunnies become Corrupt Bunnies/Crimtane Bunnies. Those spawned from Statues are Corrupt/Crimtane, and they do not revert to regular Goldfish or Bunnies after the Blood Moon is over. If it is raining during the event, transformed Goldfish will flop around on the ground.
Sold items[edit | edit source]
- The Merchant sells Throwing Knives.
- The Arms Dealer sells Silver Bullets.
- The Clothier sells the Mime Mask, Fallen Tuxedo Shirt and Fallen Tuxedo Pants .
- The Dryad stops selling Purification Powder, Sunflowers, and Grass Seeds.
- The Painter sells Evil Presence painting.
- The Steampunker sells Purple Solution (if the Corruption is present) or Red Solution (if the Crimson is present) instead of Green Solution.
- The Cyborg sells Rocket II ammunition.
- The Skeleton Merchant sells the Slap Hand during hardmode.
Other effects[edit | edit source]
- Deathweed blooms. Blood moons (and full moons on Desktop version) are the only times you can harvest Deathweed Seeds from Deathweed.
- Most NPCs have their own unique lines commenting on the event. Female NPCs act annoyed or rude (except for the Party Girl).
- As said before, water will turn red, including rain. A red filter will be applied to the screen as well, shifting the colors of all entities and light towards reds and purples. 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. However, this doesn't seem to work on mobile version.
- 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).
Tips[edit | edit source]
- 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.
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.
- Because of the celestial significance of the moon in Earth's sky, combined with its tendency to change its apparent color, the moon symbolically or literally turning the color of blood is a recurring theme in historical and popular contexts, repeatedly appearing in books, movies and video games as an ill omen- and often being treated as one when it occurs in real life.
- One of the earliest references to a blood moon appears as one of the "Seven Signs of the Apocalypse" in the biblical book of Revelation, which states, "And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;..."
- When a real Blood Moon occurred on April 14, 2014, a warning was jokingly announced on the official Terraria forums.
- During a Blood Moon, most female NPCs use more irritable or aggressive dialogue than normal. This may be a reference to the menstrual cycle.
