Sanguine Eclipse

The Sanguine Eclipse casts its sinister, bloodstained shadow across the land. Amidst the darkness of its eternal embrace, the moon emanates a sanguine glow, appearing as if droplets of blood were cascading from its obscured body. This harrowing sight holds a malevolent sway over Luyarnha, igniting the minds of the populace with a maddening rage that consumes reason and compassion, exposing the frailty of bonds forged in love and trust.
When the Sanguine Eclipse is visible, the following effects apply to the world.

Creatures

• The moon beckons. Any creature that stays under direct moonlight for more than 1 minute at a time must succeed on a Madness DC Wisdom saving throw or gain a short-term madness.
• The Scent of blood and fear is thick in the air. Beasts gain advantage on attack rolls against frightened creatures.
• The despair wrought by the celestial body is contagious. When a creature not currently under the influence of the Sanguine Eclipse (i.e., that isn’t under the influence of a madness gained under a Sanguine Eclipse) sees one of its allies fall unconscious, it must succeed on a Madness DC Wisdom saving throw or automatically gain 2 failed death saving throws the next time they fall unconscious as a result of falling to 0 hit points. This curse of inescapable doom lasts until the moon sets or if it is removed by the remove curse spell or similar magic.

Travel

A bloody miasma dimly lights the streets of Luyarnha. The maddening influence of the moon makes traveling under a Sanguine Eclipse near impossible, unless protected from direct moonlight (see Creatures, above).

Madness

The madness section of each moon refers to a Madness DC, which is indicated in the following table.

Whenever a character gains a madness under the Sanguine Eclipse, they must succeed on a Madness DC Wisdom saving throw or become frenzied for the duration of the madness or until the moon sets, whichever is shorter. While frenzied, they view their allies as enemies and must use their turns attempting to kill them. They prioritize killing in order of affection, meaning the closer they are to a person, the stronger the urge to kill them, with the strongest being that between mother and child. Characters that are immune to the charmed condition or have advantage on saving throws against charm effects have advantage on this saving throw.

Short-Term

Whenever a character gains a short-term madness under the Sanguine Eclipse, they grow claws to rip through the body of their new-found prey. They can use these claws as unarmed strikes, using their Strength or Dexterity modifier for attack and damage rolls (whichever is higher), and dealing 1d8 magical slashing damage on a hit.

Long-Term

Whenever a character gains a long-term madness under the Sanguine Eclipse, they grow fangs capable of feeding them the blood of their loved ones. Once per turn, they can replace one melee attack with a fang attack, using their Strength or Dexterity modifier for attack and damage rolls (whichever is higher). On a hit, the fangs deal 1d6 magical piercing damage and the character gains half the damage dealt in temporary hit points. In addition, the character develops sunlight sensitivity for the duration. While in sunlight, they have disadvantage on attack rolls, as well as Wisdom (Perception) checks that rely on sight.

Indefinite

A character that gains an indefinite madness under the Sanguine Eclipse begins to succumb to their newfound bloodlust.
Roll a d100:

on a result of 33 or lower, the character can ignore the effects of gaining a madness under the Sanguine Eclipse until the current eclipse sets

on a result of 34 or higher, their creature type becomes undead, and when they hit with their fang attack (if they have one), they can choose to regain hit points instead of gaining temporary hit points. Additionally, they gain the urge to feed on blood. Each day that they don’t feed on the blood of a humanoid, they gain 1 level of exhaustion. They also gain a flying speed equal to their walking speed as long as they remain in darkness.

"Stay locked in and do not leave your home. A sanguine eclipse has risen tonight."
