Earthplate Armor

At first glance, this suit of full plate looks filthy and ill kept. On closer examination, you can see it is expertly crafted, and what appears to be dirt is actually the color of the metal itself. A black crystal shard is set horizontally into the front of the armor across the abdomen. Runes in the Gnome language mark its greaves and gauntlets, and the aroma of fresh earth seems to emanate from the suit.

A suit of earthplate armor functions as +1 full plate. Once per day while wearing this armor, you can activate a stoneskin effect, as the stoneskin spell. As long as this effect is active, you also gain tremorsense out to 5 feet. Both effects last for 90 minutes or until the stoneskin effect absorbs 90 points of damage, whichever comes first.

Prerequisites: Bind Elemental {ECS 51} or Craft Magic Arms and Armor, planar binding, stoneskin.

Cost to Create: 20,000 gp (plus 1,650 gp for masterwork full plate), 1,600 XP, 40 days.
