Traits

Leafy Handholds.Creatures have advantage on ability checks made to climb the wurm.

Legendary Resistance (3/Day).If the wurm fails a saving throw, it can choose to succeed instead.

If the wurm dies, a swallowed creature no longer has the restrained condition and can escape from the corpse by using 10 feet of movement, exiting with the prone condition.

Beanstalk Wurm

Wurms are enormous creatures that resemble limbless, wingless dragons, though they lack a dragon's breath weapons and keen intelligence. On the world of Eldraine, many wurms have adapted to life among the world's skyscraping beanstalks. These beanstalk wurms sport leafy growths, sustaining themselves on a mixture of natural photosynthesis and a carnivorous diet.

Cloud-dwelling giants often use beanstalk wurms as a first line of defense against those who would ascend massive beanstalks—also known as Everstalks—to intrude on their lofty palaces. Beanstalk wurms lie coiled along the length of an Everstalk with their eyes closed and their stomach flattened against the stalk, appearing to be just another enormous vine until a tasty intruder attempts to climb them.

When giants' prized pets escape Stormkeld, villages fall and new Everstalks rise.
