Is fog a wind spell or a water spell?

[Oddball]

Consensus seems to point to it being a water spell or a water/wind spell. Which makes sense. I ended up going with a "Become the wind" spell to raise EVA significantly instead of a fog to lower accuracy. Thank you all for your answers

I'd also say this is a better option unless the fog targeted all enemies....

coincedently, becoming wind could also raise AGI
