Make the effects of some wizard items work with the monk special attacks for example, Greater Magnetism 2 would effect the second tier storm strike with a 40% increase in electric damage. Same for combustion and so on.
I think it would give some more versatility to monks. I do not think it will make them over powered but it would be interesting to see some of them specialize in certain attacks. Plus then the finishing moves would also be more effective. Triple lightning for worthwhile damage.
I also believe it should be specific not based on potency strckly the elements.
