Size Alteration

As a standard action, a spriggan can, at will, change his size between Small and Large. When a spriggan becomes Large, his speed increases to 30 feet, he gains +12 Strength, –2 Dexterity, and +6 Constitution, and he takes a –2 size penalty to his AC. While Large, a spriggan cannot use his sneak attack or his racial spell-like abilities.
