Blood Moon

, also known as Red Moons, Nights of the Red Moon, and The Hour of the Blood Moon is an event in  and.

NaN Blood Moons occur at midnight on nights when BotW:'s power reaches its peak and escapes from BotW:'s control within BotW:, dyeing the night sky and the Moon red with BotW:. The effects of this BotW: revive any fallen monsters and enemies, returning them to where they once were prior to being slain. In addition to reviving enemies and Overworld NaN Bosss, NaN Ore Deposits are replenished, and NaN Materials ranging from plants and trees, to gear left lying in the field, effectively respawn, allowing BotW: to collect them again if the ones he took before the BotW: broke in the interim period. Mechanically, NaN Blood Moons are a way to refresh 's long-term memory and appear to purge the game's cache. Consequently, data stored within the game's long-term memory is reset, including the presence or lack of NaN Materials and NaN Weapons. NaN Blood Moons do not affect things handled through short-term memory, such as NaN Creatures, BotW:, NaN Trees, and NaN Barrels. NaN Blood Moons also do not affect storyline progression, side quests, and major bosses such as BotW: and the NaN Bosss inside the NaN Divine Beasts. NaN Blood Moons typically occur after roughly 3 hours of gameplay, although one can be induced if the player kills vast amounts of enemies and picks up vast amounts of loot in a short time. If you are in the middle of a boss fight and a blood moon appears, the boss's health is completely regenerated, causing you to have to start from the beginning. NaN Blood Moons can be interrupted by entering specific areas such as NaN Ancient Shrines and BotW: before midnight (and mini-games) though the game will simply try to spawn one the next night. NaN Blood Moons are always represented by a full BotW: regardless of which phase the BotW: is in.

The effects of the BotW: begin around 11:30 PM, though the BotW: itself can usually be seen as early as 10:00 PM when the BotW: rises into the sky. At 11:30 PM, BotW: will rise from the ground, like when Link is aboard a corrupted BotW:, around NaN Pool of Malices, or on the grounds of BotW:. At 11:50 PM, the sky will turn red, and the clouds will begin to fly by very fast. When midnight hits, a cutscene begins where the Blood Moon has risen, and monsters are seen respawning across Hyrule. Princess Zelda telepathically informs Link that the Blood Moon has risen and urges Link to be careful. After that, the Blood Moon dissipates. If Link attempts to circumvent a Blood Moon by staring into a Campfire or sleeping in a Bed, the cutscene will still play. This can frighten players who have let their guard down, as the sudden loud roar and glow of red can catch them off guard. Also if Link passed time staring at a campfire in an empty enemy camp, the sudden resurrection of the enemies can catch him off guard.

BotW: of the BotW: is the primary source of information on NaN Blood Moons, and can be seen acting strangely during the time period that it affects the overworld. The player can know during the day if tonight will be a Blood Moon, as if they ask Hino what moon will be out tonight, he'll say; "I'm getting that feeling again... Something is going to happen tonight. I can taste it."

BotW: during this time gives BotW: an effect boost (even 30min level 3 effect boost). This time period can be easily identified, as specks of BotW: linger in the air for those 45 minutes, or by determining if Hino is still acting strange. If he has returned to normal, the effect has worn off, and Link must wait for the next Blood Moon.

During the Scenario "All Hyrule, United", a Blood Moon rises following the Divine Beasts bombarding Calamity Ganon with their lasers after Zelda banished the protective barrier, reviving all monsters that were slain during the course of the battle, then revived half of the monsters after they were re-killed by the Warriors. After the united forces of Hyrule broke through the Calamity's forces, the Blood Moon remained in the sky until Calamity Ganon was sealed again.

Following the completion of the last Scenario and the start of the postgame, Blood Moons start appearing. They turn Scenarios into Blood Moon Battlefields. These Blood Moon Battlefield events enhance the enemies of past Scenarios, one Scenario per waxing, changing the icon of the boosted Scenario into a Blood Moon icon, raises the recommended levels by up to sixfold, and colors the map with a red filter. It also improves the quality of Weapon drops, and increases their frequency.

When a Blood Moon rises, it changes the map theme to its "Amid the Calamity" version. Other than doubling the Rupee counts after completing the Scenario battles, including the Divine Beast combat segments, nothing else changes.

It is up to random chance which Scenarios becomes a Blood Moon Battlefield, and the frequency of the Blood Moon waxing is erratic, ranging from a Blood Moon rising immediately after clearing a Blood Moon Battlefield to after several battles. Potentially, a Blood Moon could rise over the same Scenario twice in a row. If players go to Challenge maps or other Scenario maps, it resets the Blood Moon Battlefield.

Trivia

 * An odd exception to the BotW: failing to trigger at midnight while in BotW: is during the first fight against BotW:. If midnight strikes on a BotW: night during this first battle, BotW:'s health will refill to maximum as if neither BotW: nor the NaN Divine Beasts had done him any damage. Strangely, this exception does not apply to the battle against BotW:.
 * Sometimes, a glitch can occur where a Blood Moon occurs during 12;00 PM rather than 12;00 AM. This can be due to the in time game clock suffering a glitch or places (example Colosseum Ruins area, Death Mountain hot spring area (if Link using magnesis rune in Goron's minecart and exist in Death Mountain)  acts no different than any other Blood Moon as it respawns all enemies and loot.
 * The sky turning red at 11:50 PM also occurs when BotW: reveals its core, allowing Link to deal the final blow.
 * When the console is using 90% or more of its system memory, a panic BotW: can be triggered as part of a garbage collection routine. This allows the console to clean up its system memory and restore performance to an optimal state. This can occur at any time of day and is otherwise no different than a naturally occurring blood moon.
 * Unlike with the other three Divine Beast battles, Blood Moons can occur during the Vah Rudania battle. If this happens, the Sentries will not be revived, but the Moblins in the area will.
