Useful or valuable qualities; resources (6)
I believe the answer is:
assets
I believe this is a double definition.
'useful or valuable qualities' is the first definition.
(I've seen this before)
'resources' is the second definition.
(I've seen this in another clue)
(Other definitions for assets that I've seen before include "Valuable property" , "One's total goods" , "One's valuable possessions" , "Stance discouraging particular action" , "worldly goods" .)
