  You become a larger, awful version of yourself. You grow to size Large, and take on features that horrify your enemies. You gain the following abilities: a +6 size bonus to Strength, a +4 size bonus to Constitution, a +6 Natural Armor Bonus, DR 10/magic, and spell resistance equal to 10 + half your Caster Level. You also emit an aura that emanates 30 feet from you. Enemy creatures within the aura are Shaken. Each time a creature Shaken by this aura hits you with a Melee Attack, that creature becomes Frightened for 1d4 rounds, though at the end of that duration it is no longer affected by this aura. The aura's effect is a Fear and mind-affecting effect.
