False Appearance. While motionless, the treant is indistinguishable from a tree.

Flammable. If the treant takes fire damage, it catches fire, taking 10 (3d6) ongoing fire damage, unless it is already on fire. It can use an action to extinguish itself, ending the ongoing damage.

Forest Speaker. The treant can communicate with beasts and plants.

Siege Monster. The treant deals double damage to objects and structures.


Multiattack. The treant makes two attacks, or makes one attack and uses Animate Plant.

Slam. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 20 (4d6 + 6) bludgeoning damage.

Rock. Ranged Weapon Attack: +10 to hit, range 60/180 ft., one target. Hit: 15 (2d8 + 6) bludgeoning damage.

Animate Plant. The treant magically animates a Large or larger plant within 60 feet. The plant is immobile, but it acts on the treant’s initiative and can make slam attacks, or rock attacks if there are rocks to throw within 10 feet of it. Non-plant creatures treat the ground within 15 feet of the plant as difficult terrain , as surrounding roots conspire to trip and grasp moving creatures. The plant remains animated for 1 hour. If the treant uses this action while it has three plants animated in this way, the plant that has been animated the longest returns to normal.

Legends and Lore

With an Arcana or History check, characters can learn the following:

DC 10 Treants are ancient trees awakened by powerful magic. A treant’s natures reflects that of the forest it protects.

DC 15 Like normal trees, treants are particularly susceptible to fire and the woodman’s axe.

DC 20 When threatened, treants can call upon other forest inhabitants for aid, and may even animate nearby trees to serve them.


In the oldest forests, where the song of creation still echoes and druids meet to honor nature with sacred rites, the most mature trees awaken as treants. Closely resembling the trees they once were, treants are roused when their forest is threatened, bringing to bear the strength of nature itself against their foes.

Perceptive Protectors. A treant spends much of its time living as a tree, aware of its surroundings even while rooted in place. Events taking place even miles away are perceivable to the treant based on subtle changes in their environment. Ancient treants can magically call upon the denizens of the forest for aid, sending animal messengers to deliver news, animating plants to entangle and ensnare intruders, and summoning wild creatures to drive off their enemies.

Wild Reflections. Treants and forests reflect each other—as one changes, so does the other. Airy forests, home to good elves and unicorns, produce kind treants, while dark forests full of evil spawn spiteful, twisted treants. Just as trees sometimes rot from within, so too can a treant become hollow and heartless, and as they change, the forest also grows eerie and cold.
