Flora Colossi have bodies made of wood, as such, they have resistance to being bluntly attacked but are weak to fire, if hit with fire, their bodies will catch fire, and their natural regeneration will stop until the fire is extinguished. 

Flora Colossi cannot don armor, and have a natural armor class of 10 + Con. 

Because they are "Half-Ents" they also do not need to sleep or eat and may remain awake in a trance-like state and still gain the benefits of a full rest. 

Flora Colossi use photosynthesis to eat, and in sunlight, they continue to grow new tissue. When in sunlight Flora Colossi gain 5 hit points at the start of each turn, unless they catch fire. 

Flora Colossi are known for being slow and methodical, but also extremely strong and hardy. This gives them extreme Strength and Constitution but terrible Dexterity. 

Being born from the world of Treants, at level 5 Flora Colossi can assume a Treants stature for 1 minute per long rest.

When you use this ability, your size becomes large, your unarmed melee attacks become 1d10 + your Strength modifier and you gain a reach of 15 ft. 

Flora Colossi can speak in Druidic. While they can understand Common they cannot speak it.
