Magician, sorcerer (6)
I believe the answer is:
wizard
I believe this clue is a double definition.
'magician' is the first definition.
(I know that magician can be written as wizard)
'sorcerer' is the second definition.
(I know that sorcerer can be written as wizard)
(Other definitions for wizard that I've seen before include "Expert <" , "Fantastic" , "Marvellous" , "Magician, necromancer" , "Hotshot" .)
