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.
Doubletyped. For the purposes of features, spells, and traits, the fiendbloom creature’s type becomes fiend and plant .
Dreaded Winter. When the fiendbloom creature takes cold damage equal to or greater than its proficiency bonus, its Speed is reduced by 10 feet until the end of its next turn.
Hellspore Seeding. When a fiendbloom creature dies it explodes with hellspores in a 30-foot radius. Each creature in the area makes a Constitution saving throw DC 18. On a failed save, the creature becomes infected with hellspore blight.
ACTIONS
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.
Plant creatures are magical fungoid or plant-like creatures. Ordinary plants, such as trees, are not plant creatures. A treant is an intelligent plant creature that resembles a tree.
