Ah well his pistols don't have any element they just cast simple spells so they can't cast any elemental spells.
The bullets are where the element lies in the revolver though it's main element is fire, he can only load one element worth of bullets, so basically, six wind, six water, six thunder, six fire, etc. He has to empty it completely to change the element.
The rifle is a mixture of all but he can't fire normal spells out of them only large ones.
Did I answer that one correctly?
