Take advantage of an adventure (7)
I believe the answer is:
exploit
I believe this clue is a double definition.
'take advantage of' is the first definition.
(synonyms)
'an adventure' is the second definition.

(Other definitions for exploit that I've seen before include "Feat, accomplishment" , "Heroic feat" , "Bold and daring feat" , "Take unfair advantage of" , "Feat; make use of" .)
