Armor Description

Mountain Plate

Made of thick metal plates bolted and fused together, this exotic heavy armor is incredibly massive. The suit includes plated gauntlets, metal-shod boots, a heavy helm, and reinforced joint guards.
A character wearing mountain plate cannot run. When wearing mountain plate, a dwarfs speed is reduced as if he were not a dwarf (just as heavy armor would typically reduce the speed of a human or any other character who is not a dwarf).
Mountain plate is dwarven armor, so a character with the Dwarven Armor Proficiency feat is considered proficient in its use.
Mountain plate constructed of any material that would reduce its armor category from heavy to medium (such as mithral) gains all the benefits of the material except the armor category reduction. For example, mithral mountain plate would be heavy armor with a maximum Dexterity bonus of +2, an armor check penalty of -6, and an arcane spell failure chance of 50%. The wearer's speed remains as given for normal mountain plate.
