The normal blood moon in Zelda, that is, the red moon, is a seven-day game time. The more monsters a player kills, the faster the blood moon will be.
Then when the Red Moon comes, she will go to the Feroni Tower to find durian, life radish, energy bass, sword banana, sword grass and goblin pools to collect all kinds of rare plants and goblins. You can also go to the royal sword, talent axe, Mori bow, wooden arrow and other armed supplies.
