Special Abilities
Rotting Grasp (Su): On a successful melee touch attack, a wooden armor, shield, or weapon suffers half its maximum hit points in damage and gains the broken condition—a second hit destroys the item. Magical varieties of these items receive a Fortitude save DC 22 to avoid this effect. The save DC is Constitution-based. Plants suffer 6d6+9 points of damage from this attack.

Arboreal Nemeses are the evil counterparts of treants and also their mortal enemies. The treants’ hatred for arboreal nemeses runs so deeply that they have been known to hunt them down with almost fanatical zeal. Arboreal nemeses respond in kind, hating all good things with unbridled passion, most especially beauty.

Arboreal nemeses purposefully study a potential foe before attacking to glean its motives and strengths. The cunning arboreal nemeses often attempt to parley with intruders, convincing them that they are treants or tree spirits. If all else fails, they attack with their razor-sharp claws and attempt to trample the enemy.

Arboreal nemeses loathe both creatures and objects of beauty. They destroy or bury any treasure they consider beautiful, such as a flawless diamond or a sapphire necklace. Conversely, there is nothing arboreal nemeses love more than corrupted beauty; therefore, arboreal nemeses often retain flawed objects as part of their treasure.

On Porphyra
The most feared gathering of arboreal nemeses is the Harrowing. The Harrowing is a dark alliance between a group of arboreal nemeses, a horde of lesser forest creatures, and an evil druid. It is fortunate that such meetings are rare, for the union of these evil beings can quickly transform a light, airy forest into a dark, brooding hunting ground for twisted, malevolent creatures.
