True Self

You touch a willing creature that is not an undead or a construct and temporarily alter their physical form in accordance with their wishes. The creature can change their race, gender, body type, or any other aspect of their physical appearance. If the target changes their race through this spell, they lose all the racial abilities and bonuses from their current race and gain those of the new race, except for languages spoken.

After 30 days, the enchantment begins to fade and the target will revert back to the form they possessed before the casting of the spell.

Casting this spell on the same creature and choosing the same alterations each time every 30 days for a year will make the spell's effects permanent.
