Well, actually, KevinTheDestroyer, I would find them practically useless against a Leviathan.

However, one like Lot's Salt, like it did with an Archangel's vessel, disintegrate the body they're using.

Maybe together they could cause a Leviathan great damage, as it would've to Raphael, in an attempt from Cas.

basically, no use against them.
