Transformation Spell

A Transformation Spell is one of the most common form of magic shown in the SF universe. While not all transformations seen are based in magic most of them are to an extent. Transformation magic is Gold focused and is used to transform people or objects into a different form. Most commonly seen to transform characters from one gender to another. The Sorcerer merely needs to focus their spell on an individual and visualize how they want to transform them. They can also transform themselves in various ways. Transformation magic is somewhat basic compared to others and seems to be learned early on by sorcerers as Claire Dupont was able to fully transform a teenage boy into a teenage girl at age 12 (Little Witches) suggesting she just recently learned how to transform other people. Most sorcerers learn to transform themselves, other people and inanimate object rather easily but can usually only alter their shapes (and/or Gender) only Gold Blooded Sorcerers are able to actually transform their own or other bodies into different materials such as turning them into Steel or other metal to be more resilient.
Some practices of transformation magic can in fact create a Transformation Stone which is usually seen as a rounded gold colored orb or a special crystal witch can be enchanted to either allow one person to swap back and forth freely between two forms without using their own magic (or even if they don't have magic themselves) or allow one individual to use it like a quick change spell deadlocked to transform them back into themselves in the event their transformation experiences any side effects.
One side effect of transformation magic is that if you transform into another living person after so long your mind begins to fade and black out to the point where you think like the person you've turned into and reach the point you believe you are them. to the unexperienced this can occur within a few hours but to the trained it can take days to happen or even be avoided all together by the proper master. This side effect does not seem to occur if the transformation is more focused on simply altering the body into a new and/or improved shape such as gender swapping or increasing muscle or curve size. Since you transformed your own body into a new form instead of the form of someone else your mind stays perfectly intact.
