A massive wave of platinum pieces comes crashing in over all creatures in a 40ft square centered on a point of your choice within 550ft of you, bludgeoning them with money and forcing them to make a strength saving or take 12d6 bludgeoning damage and be knocked prone or half as much on a successful saving throw. if they get a natural 1 all of the platinum coins stay in existence instead of fading away which they will otherwise.
