🌕 Blood Moon

Blood Moon is an atmospheric gameplay mod for Valheim that introduces a rare and dangerous night event - the Blood Moon.

Once every few days, the night turns crimson. The moon glows blood-red, the world is drowned in red fog, and enemies become temporarily stronger and more numerous. At dawn, everything returns to normal.
