You dont need to eat as long as you are exposed to sunlight for 8 hours a day, or artificial bright light for 12 hours a day. If you do not have access to either of these, you must consume a corpse of a creature at most one size smaller than you, there is no limit to how many corpses or the size of the corpses you can consume, this does not work with: undead, constructs, or elementals.

Treants start from just under 3 to over 5 feet tall at a young age, increasing with size and maturity, at level 1, you are small, at level 5, you are medium, at level 11, you are large, at level 17, you are huge

You dense bark and lengthy lifespan, no matter what age you are, make your body naturally much stronger, and your mind sharper and wiser. Your Constitution score increases by 2, your Wisdom score increases by 1, and your Strength score increases by 1.

Even though you are made mostly out of wood, your sap and bark is often wet enough to not take significant damage, but the area where the fire was is burnt off, it will regrow and magically regenerate partially in 1d4 days, and fully heal after a year.

When you take Fire damage from any source, you have disadvantage on all attack rolls until the end of your next turn.

Treants can often live for centuries, almost as long as elves, and can even live indefinitely if the ground is healthy and bountiful in minerals and can sustain them properly, 1 year to an ent is like one second to a human

Treants are noble and steadfast protectors of the forest, doing whatever it takes to protect it and ensure it's survival. Hence, they tend toward neutral good or chaotic good, putting the forest and it's inhabitants before alien live.

Due to thier extensive root structure, Treants often root themselves in place, extending tiny worm like roots in a 60ft radius around them, a process which takes about an hour, most treants use this ability when resting and keeping watch, after one hour, you gain tremorsense up to 60ft, unrooting takes one hour, leaving the ground untampered with, or as an action if the Treant chooses to tear itself out of the ground, leaving a sizable hole and debris around where it rooted, usually used when it's grove was snuck up on.

If the Treant chooses to tear itself out of the ground, it takes 6d10 psychic damage, and this damage can only be a maximum on 1/4 of the Treant's current health.

You can attack while rooted, but you are restrained with no disadvantage on attacks, and you cannot be moved against your will unless the ground you're on is displaced.

Rooting and unrooting normally do not intefere with a long or short rest, but tearing itself out of the ground does, if the Treant has rested for more than one hour, it gains the benefits of a short rest.

You have advantage on saves against being charmed, and magic can’t put you to sleep. If you are forced to do anything directly harmful to a forest, like spreading salt on the roots of trees or starting a fire, any effect forcing you to do so immediately ends.

Treants don't need to sleep, Instead, they sit in one spot and keep watch, often going through thier day and reviewing what happened throughout the night

You can cast the enlarge/reduce spell at will, targetting yourself only as you draw sustenence and energy from your surroundings

Once per day, you can cast goodberry as you pluck fruits and nuts from your branches, each fruit you create and pluck take 1 psychic damage.
