  This spell causes a brushy beard of stiff iron to erupt from the face of a willing target. The ironbeard grants a +1 Armor Bonus to AC, and this bonus stacks with any armor worn by the creature. The ironbeard may also be used as a weapon equivalent to Cold Iron armor spikes. The ironbeard makes it difficult to speak, so any spellcasting with a verbal component has a 20% spell failure chance.
