Venomous Breath

The Serpentis Draconis releases a 30-foot cone of venom, forcing all creatures within to make a DC 15 Constitution saving throw, taking 36 (8d8) poison damage on a failed save, or half as much damage on a successful one. The dragon cannot use this ability again until it finishes a short or long rest.

Monster Description

The Serpentis Draconis is a mythical creature resembling a dragon but made up entirely of writhing snakes. Its dangerous presence can be felt before it is seen, as the sound of hissing fills the air. This creature is said to guard ancient secrets hidden deep within cursed forests and forgotten ruins. Its massive form can coil through trees, blending in with the environment, making it formidable for unsuspecting adventurers.

Monster behavior

The Serpentis Draconis is territorial and will attack intruders fiercely. It uses its venomous breath to incapacitate foes, followed by powerful bites to subdue them. Its unique weakness lies in its core, which can only be attacked when it is incapacitated. As such, it will often feign weakness to lure attackers into a false sense of security, making it extremely cunning in combat.

Ecology

In the ecosystem, the Serpentis Draconis represents the apex predator of its habitat. It controls the population of smaller creatures, ensuring balance in the local fauna. Legends say that its venom can cure certain ailments, yet it is equally feared for its lethality. The presence of a Serpentis Draconis indicates an area rich with magic and danger, often attracting adventurers seeking fortune or knowledge.

History

The Serpentis Draconis has been a part of local folklore for generations. Many tales speak of its immense power, cunning nature, and the treasures it guards. Stories of adventurers facing it abound, with few surviving to tell the tale. Some accounts claim that it was once a guardian of nature, corrupted by dark magic, transforming into the fearsome beast it is today. Its very existence poses philosophical questions regarding nature, magic, and the balance of good and evil.
