Twisted element of magic in a Tasmanian devil's character (7)
I believe the answer is:
satanic
'devil's character' is the definition.
(like Satan)
'twisted element of magic in a tasmanian' is the wordplay.
'twisted' is a reversal indicator.
'element of' indicates the answer is hidden within the clue (I've seen this in other clues).
'cinatas' is hidden in the letters of 'magic in a tasmanian'.
'cinatas' in reverse letter order is 'SATANIC'.
(Other definitions for satanic that I've seen before include "like Mephisto" , "Diabolic" , "Like the Devil" , "Relating to the devil" , "Very evil and cruel" .)
