Polymorph, Greater (Wyvern)

You are in wyvern form now. You have a +4 size bonus to your Strength, a –2 penalty to your Dexterity, and a +4 natural armor bonus to AC. Your movement speed is reduced by 10 feet. You also have one sting attack (1d6 plus poison), one bite attack (1d8), two talon and two wing attacks (1d6 each). You may choose to resume your normal form as a full-round action; doing so ends the spell for you.
