Wielded by wealthy Taldan knights against the Goroth Lodge, this +1 striking returning hatchet has an axe head resembling a roaring lion's head.


Activate—Slash and Burn (manipulate)
Trigger You critically succeed at a Strike against a plant
Effect The weapon's etchings pulse with green energy, as it tears through bark, leaf, and wood. The clear cutter's axe deals an additional 1d10 persistent fire damage to the plant.

Activate—Mow Down (manipulate)
Frequency once per day
Effect You hurl the axe horizontally, sending it flying through the air in a wild, whirling cyclone. The axe flies in a 30-foot emanation around you, eliminating all non-magical undergrowth and any resulting difficult terrain, cover, and concealment in area. It attempts to counteract one magical effect that affects a plant in the area (counteract +20). Plant creatures in the area take 5d6 slashing damage (DC 25 basic Reflex save). As the axe finishes its circuit, it returns to your hand.
