You gain a +3 bonus to attack and damage rolls made with this magic weapon. While holding it, you ignore difficult terrain and you are resistant to piercing damage.

This warhammer also has 3 charges. As an action, you can expend 1 charge to slam this hammer into the ground and cause the roots of the Worldtree to erupt in a 20 foot radius from a point you can see within 120 feet. The radius becomes difficult terrain for 1 minute. Any creature within the radius must make a DC 20 Dexterity saving throw. On a failure, a creature takes 6d6 piercing damage and is restrained by the entangling roots. On a success, a creature takes half damage and is not restrained. A creature can use its action to make a DC 20 Strength check, freeing itself or a restrained creature within their reach on a success.

The warhammer regains its charges daily at dawn.

Proficiency with a Warhammer allows you to add your proficiency bonus to the attack roll for any attack you make with it.
