Draw on fortune to produce weapon (5,4)
I believe the answer is:
smoke bomb
'weapon' is the definition.
(type of weapon)
'draw on fortune' is the wordplay.
'draw on' becomes 'smoke' (as in drawing on a cigarette).
'fortune' becomes 'bomb' (both can mean a large amount of money).
'smoke'+'bomb'='SMOKE-BOMB'
'to produce' acts as a link.
(Other definitions for smoke bomb that I've seen before include "Weapon obscuring vision" , "Weapon providing concealment" , "Explosive device used to obscure activity" , "this may cover aggressive activity" , "Explosive position marker" .)
