SPECIAL TRAITS

• False Appearance. While the treant remains motionless, it is indistinguishable from a normal decaying tree. Lifeless Aura. The Acheron-corrupted treant exudes an aura of deterioration and lifelessness that manifests as an unpleasant itching up to 20 feet from the treant. Creatures in the aura other than fiends and Acheroncorrupted creatures can’t regain hit points.
• Siege Monster. The treant deals double damage to objects and structures.

ACTIONS

• Multiattack. The treant makes two slam attacks.
• Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage.
• Rock. Ranged Weapon Attack: +10 to hit, range 60/180 ft., one target. Hit: 28 (4d10 + 6) bludgeoning damage.
• Animate Trees (1/day). The treant magically animates one or two trees it can see within 60 feet of it. These trees have the same statistics as an Acheron-corrupted treant, except they have Intelligence and Charisma scores of 1, they can’t speak, and they have only the Slam action option. An animated tree acts as an ally of the treant. The tree remains animate for 1 day or until it dies, until the treant dies or is more than 120 feet from the tree, or until the treant takes a bonus action to turn it back into an inanimate tree. The tree then falls over and dies.

ABOUT

The desolation and barrenness that accompany the Acheron legion have warped this treant, imbuing the creature with the malevolent desire to spread its own decay. The forest creatures that once depended on the treant’s guidance now suffer under its depredations, and the treant’s former domain is now a blighted haven for evil. Fiends use corrupted treants as living siege engines, assaulting the fortifications of elves and other intractable creatures that seek shelter in the forest.

This lumbering tree looks badly diseased, with patches of rot on its trunk and decaying leaves clinging to its boughs.

Acheron Corruption

Acheron corruption is usually embraced by creatures living in the desolate, barren wastelands that the Acheron legion produces, if only as a means to survive. While this legion controls an area, live births from any creatures are rare and produce corrupted creatures that grow to maturity with supernatural speed. Creatures with an Acheron corruption seem sickly and pale, and most have vacant, hollow gazes.

Acheron corruption grants the following trait.

Lifeless Aura. The Acheron-corrupted creature exudes an aura of deterioration and lifelessness that manifests as an unpleasant itching up to 20 feet from the creature. Creatures in the aura other than fiends and Acheron-corrupted creatures can’t regain hit points or gain temporary hit points.
