6th-level transmutation
Casting Time:1 action
Range: touch

The target you touch undergoes a rapid change, transforming into an elf, if it fails a Constitution saving throw. The target’s type changes to humanoid (elf), and it loses all race abilities. However the target gains fey ancestry, trance, and keen senses. It still has all it’s original statistics. After 1 day, the elf changes back into its old race. If the spell is repeated for three days, and the save is failed each time, the spell becomes permanent.
