Mountain dwarf masons and wizards crafted this battleaxe to wield while defending their cities from invading duergar. The axe is a single piece of stone carved with Dwarvish runes. You gain a +1 bonus to attack and damage rolls made with the battleaxe. In addition, whenever you hit an object or creature made of stone or earth (such as an earth elemental or stone golem) with this weapon, you deal an extra 2d8 thunder damage to the target. If a creature takes thunder damage from this weapon, it must succeed on a DC 15 Strength saving throw or be knocked prone.
If you are attuned to the stonecutter axe and attuned to the stoneguard armor and the stoneshaper ring, the bonus to attack and damage rolls you make with this weapon increases to +2.
Proficiency with a battleaxe allows you to add your proficiency bonus to the attack roll for any attack you make with it.
