Total Polymorph

The user is able to change one body races, subraces, species and subspecies, to another. It can only be done once per year. And True Polymorph, Wish, any any other similar this and those spells fail automatically, and as does Divine Intervention in any attempt either also. The character changed, also is at half Hit Points after changed. Should not be used in combat, but likely, most of the time, while adventuring.
