Unstable Mutation

The mutated genes overwhelm you with their power, shifting your very essence. You gain the following benefits:

• Your Form of the Beast feature manifests even if you are not raging. You choose the natural weapon to manifest when you pick this feat and you cannot change it.
• When you enter your rage, you shapeshift completely, manifesting all the natural weapons instead of choosing one of the options.
• While shapeshifted, your speed increases by 10 feet.
• While shapeshifted, you can't wield any weapon and/or shield, you walk on all fours and you can't speak any language (you can still read and understand them, but not write nor speak).
