Attractive trap in sorcery (8)
I believe the answer is:
magnetic
'attractive' is the definition.
(synonyms)
'trap in sorcery' is the wordplay.
'trap' becomes 'net' (net is a type of trap).
'in' means one lot of letters goes inside another.
'sorcery' becomes 'magic' (I've seen this in another clue).
'net' inserted into 'magic' is 'MAGNETIC'.
(Other definitions for magnetic that I've seen before include "Very attractive or alluring" , "Drawing" , "attractive result" , "What's attractive" , "Attracting iron or steel" .)
