race features:
Barkskin
Treefolk cannot wear armor, but their bark-like skin provides them with some natural protection. A Treefolk's Armor Class equals 10 + their Dexterity modifier + their Constitution modifier. Treefolk can use a shield and still gain this benefit.
Take Root
Treefolk do not sleep, but they must put down roots each night and enter a semi-conscious dormant state similar to an elf's trance for at least 6 hours. Treefolk can take root in sand, dirt, mud, loose gravel or similar material; but not worked stone or bare rock. While rooted, a Treefolk's speed becomes 0, and they become immune to both the prone condition and any form of forced movement, but have disadvantage on Dexterity saving throws. Treefolk may root or uproot themselves as an action.
Flammable
Treefolk have vulnerability to fire damage. Treefolk are weak to fire, and burn easily.
Thick as a Plank
Treefolk have resistance to non-magical bludgeoning damage.
Non-Humanoid
Treefolk are not subject to spells and effects that target humanoids, such as Charm Person. They count as plant creatures for the purposes of spells which target plants such as Blight.
Immunities
Treefolk are immune to sleep effects.
Physical Description
As their name implies, Treefolk resemble walking trees. Their torso resembles a tree trunk, stumpy legs and root-like appendages for toes; long boughs for arms and long branch-like fingers, a torso resembling a treetrunk, very little neck, and a face framed by thin, leaf-filled branches instead of hair. Each Treefolk's leaves and bark strongly resembles a specific kind of tree, such as birch, elm, oak, pine, etc. Treefolk breathe and can eat or drink, though most treefolk absorb nutrients by taking root at night. Depending on the type of tree they resemble, the leaves that make up their hair may change color or even fall off with the changing of the seasons.
Treefolk are medium creatures, but grow to be nearly ten feet tall. They usually do not wear clothing, but can fashion belts and such to hold their possessions. Non-treefolk usually cannot tell male treefolk from females.
Whose Woods Those Are I Think I Know
Ponderous and slow-moving, treefolk tend to think before they speak, and speak before they act. Treefolk come in all varieties of temperament and alignment, often depending upon their proximity to other intelligent creatures, and whether those experiences have been positive or negative. Treefolk are solitary creatures, only gathering in small groups when the need arises. Most treefolk claim their own territory much like an animal, which may be any size up to several square miles of forest. A treefolk will aggressively defend the trees within their territory if it is threatened by invaders.
Most days for a treefolk begin and end in the forest. After sunrise, the treefolk will uproot themselves and search for a spot where they can absorb the most light possible. Part of their day will be spent wandering through their wooded territory, keeping track of all the trees in their care. Occasionally they will cooperate with druids or rangers, even asking them for aid if the threat to their lands is greater than they can handle alone. At dusk, treefolk will find a patch of rich, moist soil and root down into it for the night, absorbing nourishing nutrients and water until sunrise the next day.
Treefolk: Fond of Trees, Amazingly.
Whether living in snow-capped mountainous timberlines, swampy bogs, high desert forests, rainforests, jungles, or any other forest type, Treefolk are most comfortable among trees of their own kind.
Wandering Treefolk: Something has happened.
A treefolk spotted outside of their forest usually has undergone some manner of tragedy: a forest fire, deforestation by other races, or even occasionally defeat at the hands of a more powerful treefolk who seizes the defeated treefolk's territory as spoils of victory. A treefolk without a forest to tend to may travel far until they find another patch of woods that suits their liking. If their woods were destroyed by other creatures, a wrathful treefolk will journey as far as it takes in order to exact revenge.
