You probably can't find one because elements are pretty underwhelming in terms of damage by midway through the game. Hell, I simply use them in end game or new game+ simply to prevent the enemy from getting an advantage. Seriously, the combo/melee system can usually far out damage what elements can do with the right weapon, and when you get broken characters like Guile, whose normal heavy attack also hits all targets, the element system is pretty moot outside of getting the games true ending.
