Blood Moon

The Blood Moon is an event that occurs on random midnights in.

Overview
The Blood Moon is indicated by a red-colored full moon rising instead of a regular moon or phase. Before a Blood Moon, the environment will glow red and the air will be full of black particles. When it occurs, the Blood Moon revives all enemies and Overworld Bosses that have been defeated up until that point. The Blood Moon event starts occurring after Link leaves the Great Plateau.

A Blood Moon event can also occur even when skipping time using a Campfire, Cooking Pot, or by sleeping at an inn, as its cutscene still plays after time has been skipped. If a Blood Moon occurs when Link is in an Ancient Shrine or Hyrule Castle, the Blood Moon scene does not appear and previously defeated enemies will not be revived. The Blood Moon will occur every following night until it happens while Link is outside where the scene can appear.

Cooking from 11:30 PM to 12:15 AM on the night of a Blood Moon gives Food an effect boost.
