Blood Moon

, also known as Red Moons, and Nights of the Red Moon, are events in, as well as.

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 thereof 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 major bosses such as BotW: and the NaN Bosss inside the NaN Divine Beasts. NaN Blood Moons can be initiated by overloading the long-term memory through slaying monsters and enemies, visiting several locations, BotW: past midnight at NaN Campfires and NaN Cooking Pots, sleeping past midnight at NaN Inns, or by playing the game uninterrupted for three real-world hours. NaN Blood Moons can be interrupted by entering specific areas such as NaN Ancient Shrines and BotW: before midnight, though they will simply appear again 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, BotW: will warn BotW: that a BotW: has risen and advise him to take caution. 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. After midnight during a BotW:, BotW: will start acting oddly.

BotW: from 11:30 PM to 12:15 AM on the night of a BotW: night gives BotW: an effect boost. This time period can be easily identified, as specks of BotW: linger in the air for those 45 minutes.

Pre-Moon
There are some signs that a blood moon is approaching in a few days through a very slight tune you hear at the end of a day, people describe it as "The beginning of Omen of a Bloody Moon" or "It sounded like vrrr" Multiple people have said they heard this tune and I myself will be researching it.

Another way to tell if a Blood Moon is coming is talking to Hino at Dueling Peaks Stable, If there is a Blood Moon, he will say one of these things:

"I'm getting that feeling again, Something is going to happen tonight"

"Something's going to happen tonight, I can taste it!"

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:.
 * 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.
