Mad-eye Moody is a D.A.T.D.A. Teacher at Hogwarts School of Witchcraft and Wizardy. Barty. Crouch Junior tries to fool Mad-Eye's class in Year 4 when he disguised himself as Mad-eye. In the same year (still Bartemius in disguise) he teaches Reducto.
How to obtainEdit
Mad-Eye can be obtained in the secret dungeon under Professor Flitwick's Lumos room. To get to the dungeon, use Reducto on the padlock on the floor, then it will open up. His token can be found in there.
