Elemental Weakness added to armor and weapons

[EmilyAnnCoons 7]

I'm looking for a script that allows for me to add elemental weakness to a player wearing certain armor (example: a wooden shield would burst into flame thus making you weak to fire, while an iron shield would conduct electricity, making you weak to lightning). I'm not sure if this is possible or not, though. If so, could anyone manage to build a script like that for me?
