Gnarlwoods are grown from the seeds of treants that had the misfortune of sprouting in land cursed by an unhallow spell. The good nature of the treant is subverted by the very nourishment it gains from the earth, and the evil of the spell suffuses into its every fiber.

Most gnarlwoods die before they are much larger than twiggy saplings, since few creatures of nature can survive on a diet of pure evil. Those that do survive grow into menacing, twisted mockeries of treants, with four knobby arms that end in cruel barbed claws. Gnarlwoods are spiteful, hateful things that seek to destroy everything they see. Bereft of any compassion, gnarlwoods tear through forests accompanied by the shambling corpses of its victims, rending and clawing anything that moves.

Some evil druidic temples secluded deep in ancient forests are protected by entire groves of gnarlwoods. Unfortunately for the worshippers, not even they are spared the psychotic wrath of the gnarlwood.

A gnarlwood usually begins combat with its protection from good in effect (especially when facing good-aligned opponents) and normally sends its minions (if any) into battle to distract or soften up its foes. In the first round it attempts to use its slay living spell-like ability against a creature it deems highly susceptible (usually a wizard or sorcerer since they have poor Fortitude saves). In the next round it assaults its opponents with its claws, rending any opponent it hits with at least two of its claws. It sprinkles combat with its spell-like abilities throughout. During battle, if possible, it tries to keep any undead minions it has with it within the confines of its unhallowed aura so enemy clerics find it hard to affect them with their channel energy ability.

A gnarlwood constantly howls and wails during battle and always fights to the death.
