Stonereaver

Half of the head of this greataxe is a curved blade, while the other side tapers to a chiselpoint pick on the other. The haft looks as thought it’s made from cracked granite.

In the hands of a nondwarf, stonereaver functions as a +1 greataxe.

In the hands of a dwarf, the weapon also gains the bane property against elementals that have the earth subtype and against constructs primarily made of earth, stone, or metal.

Prerequisites: Craft Magic Arms and Armor, stone shape.

Cost to Create: 3,000 gp (plus 320 gp for masterwork greataxe), 240 XP, 6 days.
