Magician's rod (4)
I believe the answer is:
wand
'magician's rod' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wand that I've seen before include "Rod of magician or water-diviner" , "Magic rod?" , "Magician's accessory" , "Dawn (anag.)" , "Wizard's rod" .)
