An alraune's height is anything 5 to 6 feet on average, and weigh anything from 60 to 120 pounds. Your creature size is Medium.

 Your creature type is considered to be both humanoid and plant, and you can attempt to hide even when you are only lightly obscured by foliage, heavy rain, falling snow, mist, and other natural phenomena. However, you are vulnerable to fire damage.

Alraune don't need to sleep. Instead, they can root themselves in the favorable soil, remaining semiconscious, for 4 hours a day and absorbing nutrients from the soil. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep. However, if the soil is not favorable you require a full 8 hours of rest to gain the equivalent of a long rest. Rooting yourself requires an action and can only be done on a patch of soil. While in this state your speed becomes 0 and you can uproot yourself as a bonus action.

As a part of the forest, it's only natural for you to be knowledgeable about the wilderness. You are proficient in the Nature skill.

You understand and can speak Common and Sylvan.

Your Wisdom score increases by 2.

 As a sprouting seed, the alraune grow within the bulb of a particular flower for about 5 years depending on the favorability of the soil, after which they bloom into their mature state. Their bodies don't age after that but instead exhibit signs of age when they are unable to gain the nutrients they need. These signs manifest themselves as wilting vines, molting leaves and browning skin. They can live up to 750 years before returning to the earth from which they were born.
