and allow small torn on the Wings webbing and Tail tip.

This is not a full transformation into that element.
The original shape of the body part must remain unchanged.
Color changes is allowed as long as the general hue still remain purple up to black.
Elements cannot be mixed or have their properties altered (for example, fire cannot be changed into cold fire.)
