Before Combat Treerazer begins most combats by casting time stop and raising an antiplant shell to prevent plant creatures (including creatures under the effect of his aura of corruption) from approaching. If he has time, he also creates walls of thorns and summons demons (usually four nalfeshnees and 12 hezrous).

During Combat In melee, Treerazer gleefully takes up Blackaxe and makes full attacks against the closest foe, or Greater Vital Strikes if he’s forced to move or charge. During the first 3 rounds of combat, he targets obvious spell effects with quickened greater dispel magic. If Treerazer is reduced to fewer than 150 hit points, he teleports back to his fortress, Witchbole, to recover and plan his revenge.

Aura of Corruption (Su)

Treerazer exudes an aura of corruption to a radius of 120 feet. This aura causes plants to grow hideous, sprouting thorns, twisting, and becoming fungoid in nature. Creatures with woodland stride or freedom of movement can move through this fungal bloom with ease. Living creatures within Treerazer’s aura of corruption must make a DC 39 Fortitude save each round or their flesh grows pasty and clammy as tendrils of diseased plant matter and fungal growth sprout from it. This condition persists as long as the creature remains within Treerazer’s aura of corruption and for 1 minute thereafter. While suffering the effects of this aura, the living creature is treated as a plant for the purposes of spells and effects that harm or otherwise inconvenience plant creatures more than other creatures. The victim would thus be subject to antiplant shell, blight, and additional damage from horrid wilting or a plant bane weapon, and could be affected by control plants. The corruption does not otherwise impart plant traits to creatures. The save DC is Constitution-based.

Defoliation (Su)

As a standard action once every 1d4 rounds, Treerazer can exude a pulse of defoliating energy in a 30-foot-radius spread. This pulse appears as a wave of sickly green energy, and causes all plants and plant creatures in the area to blacken and wither. Such creatures take 20d10 points of damage and 1d8 points of Strength drain, or half with a successful DC 39 Fortitude save. A plant that isn’t a creature (such as a tree or a shrub) doesn’t receive a save and immediately withers and dies. Treerazer can choose to exclude any number of plants in the area from this effect, and generally does so to preserve twisted and corrupted plants and fungus. The save DC is Constitution-based.

Blackaxe (Major Artifact)

Aura strong conjuration; CL 20th

Slot none; Weight 50 lbs.


Treerazer’s favored weapon is Blackaxe, a Huge +5 plant bane greataxe carved from obsidian but as strong as adamantine—this weapon is considered epic and can penetrate epic damage reduction.

Virulent acid constantly seeps from Blackaxe’s blade, dealing +1d6 points of acid damage on a successful hit. On a successful critical hit, Blackaxe deals an additional +2d10 points of acid damage. Once per minute, the weapon’s wielder can use heal on himself by striking a living and nonmagical tree with Blackaxe—this act causes the tree to wither to ash in a heartbeat. Treerazer can call Blackaxe to his hand as a free action, despite any intervening distance, as long as Blackaxe is not kept in an area that prevents teleportation effects from occurring. The nascent demon lord often loans Blackaxe to favored minions, and uses this ability to reclaim his weapon should he become aware that the wielder has failed in a mission. While Blackaxe is wielded by another creature, Treerazer always knows that creature’s location and status (as via the status and discern location spells), and by concentrating can observe the world around the wielder as if using that wielder’s senses. While in this state, Treerazer may use any of his spell-like abilities through the link, treating Blackaxe as if it were the source of the spell-like ability. Each time Treerazer does so, Blackaxe’s wielder must make a DC 25 Will save to avoid being staggered for 1 round from the flow of power. These spell-like abilities trigger during the wielder’s turn in initiative, but do not consume any of the wielder’s actions in that round.


Blackaxe, it is rumored, was stolen by Treerazer from the demon lord Cyth-V’sug. In order to destroy it, Blackaxe must be used against a powerful magical tree, and while the sap on the blade is still fresh it must then be used to sever one of Cyth-V’sug's many fungoid limbs. Doing so causes Blackaxe to explode in a burst of obsidian shrapnel and acid that inflicts 20d6 acid damage and 20d6 piercing damage to all within a 60-foot burst (DC 30 Reflex half).
