Need some help with an idea on status effects

[Shade the Mystic]

I'm wondering if it's possible to have status ailments that make you more or less vulnerable to specific elemental attacks, for instance, like Oil in Final Fantasy XII makes you more vulnerable to fire magic, or a magnetized effect to make you more vulnerable to electricity.

If anyone has any ideas on how to make this happen, or if it's even possible, then  that would be great, I'd be very appreciative. Thanks.

There is a script out there that allows sue of oil and such as status ailments, but I donnt remember who wrote it, but It is on this forum somewhere.
