Blood Moon

The Blood Moon is an event that occurs on a random midnight in. It is indicated by a red colored full moon rising instead of a regular moon or phase. A Blood Moon event can also occur even when skipping time using a campfire.

A Blood Moon event cannot start occurring until after Link enters a region outside of the Great Plateau, which from that point on, will occur on random nights. The odds of a Blood Moon occurring will always depend on how many enemies were defeated in-between each Blood Moon that has occurred.

When it occurs, the Blood Moon revives all enemies that have been defeated up until that point.

It is also very dangerous for Link to be in an enemy's base, just after it has been cleared out, right before a Blood Moon. If players see a Blood Moon around 10pm, it is always best for players to leave the enemy base before the clock reaches 12am, otherwise Link would get surrounded and could easily get killed by the numerous enemies surrounding him.
