Reckless Wildshape

To protect the natural world from a great evil that threatens to break it, you draw upon your vitality to break through the barrier which limits the strength of your Wildshape form. By sacrificing hit dice in multiples of 2, you can increase the CR level of creatures you can transform into by 1(ex. 2 dice= +1 CR level, 4 dice= +2 CR level etc.). Only 2 creatures can be chosen per level and must follow the Wildshape rules.
