Your Strength score increases by 2, your Constitution score increases by 1, and your Dexterity score is reduced by 2.

Treants age slowly, typically maturing around 50 to 75 years of age. Most adventuring treants are around this age since “adventuring is a young tree’s game.” Like normal trees, treants can live up to 200 years and some may even reach 400 years of age.

Treants tend towards chaotic alignments and are often good.

Young treants are larger than most humanoids, standing 7 to 8 feet tall. Your size is Medium.

Your base walking speed is 25 feet.

Treant attitudes are affected by the time of year. Depending on what season it is in the campaign world, you gain traits as detailed below:

• Spring. You are in a delightful mood and positively bursting with energy. During the spring, your walking speed increases by 10 feet and you have a +3 bonus to your initiative checks.
• Summer. You are temperamental and quick to action. During the summer, when you hit with a melee weapon attack you deal 2 extra damage.
• Autumn. You are solemn yet eager to help your allies. During the autumn, when a creature that you can see targets an ally within 5 feet of you with an attack, you can use your reaction to swap places with your ally, and you become the target instead.
• Winter. Your mood is dark as you frequently reflect on life and death. During the winter, you have resistance to necrotic damage. In addition, you make all death saving throws with advantage.

While you remain motionless, you are indistinguishable from a normal tree.

Because of your unusual shape, you cannot wear armor of any type. However, your Armor Class equals 13 + your Constitution bonus. You still gain the normal benefit of using shields as long as you are proficient with them.

You take double damage from fire and fire spells and effects.

You have two creature types: humanoid and plant. You can be affected by a game effect if it works on either of your creature types.

You can speak, read, and write Common and Sylvan.
