The Grax is a craftable post-Moon Lord hamaxe that has a range five tiles larger than most other tools, and is the final upgrade of the Feller of Evergreens. Striking an enemy with it will grant the player the Grax Boost buff for 10 seconds, which increases defense by 30, damage reduction by 10% and melee damage by 20%. Right clicking with the item causes the weapon to swing without the ability to cut down trees or destroy walls.

Its best modifier is Light for harvesting purposes and Legendary for combat purposes.
