Transfera Identica is a spell that is used to switch the caster's body with someone else's. It can be used to swap others' bodies as well. The words of the spell must be said three times to be cast.
Preparing a potion is necessary, in order to cast the spell.
In A Change of Face, Charmcaster used this spell eight times. She originally intended to use the spell on Ben so she can use the Omnitrix, but Gwen got in the way and accidentally switched bodies with her instead. While Gwen was taken to a juvenile hall, Charmcaster had to prepare the potion again, but had to make sure she got it right as she was starting to be short on ingredients. Gwen arrived just in time to stop the spell. Unfortunately, while Charmcaster returned to her old body, Gwen and Ben ended up getting switched instead. Charmcaster had enough ingredients for one last potion and, not taking any chances, imprisoned the Tennysons. Gwen in Ben's body used the Omnitrix to fight Charmcaster and when Charmcaster attempted to cast the spell again, Ben in Gwen's body interferred, making sure only Ben and Gwen returned to their proper bodies.
