Accomplished wizard (5)
I believe the answer is:
adept
I believe this clue is a double definition.
'accomplished' is the first definition.

'wizard' is the second definition.

(Other definitions for adept that I've seen before include "Proficient, skilled" , "Master" , "Dexterous" , "Practised" , "Skillful" .)
