Polymorph, Greater (Large Earth Elemental)

You are in large earth elemental form now. You have a +6 size bonus to your Strength, a –2 penalty to your Dexterity, a +2 size bonus to your Constitution, a +6 natural armor bonus, and a +1 bonus to your attack, damage rolls, and combat maneuvers. You also have two 2d6 slam attacks, resist acid 20, and vulnerability to electricity. You are immune to critical hits and sneak attacks. Your movement speed is reduced by 10 feet. You may choose to resume your normal form as a full-round action; doing so ends the spell for you.
