Effect of Rain on Aggro

I have done some preliminary testing on the matter, it seems that from ranks 9 -> 1, the aggro range is reduced to 100cm. This is just within barehand melee range. I need some help confirming, but rank 1 -might- reduce visibility to 50cm. This would be when character models are basically touching. Considering what Raincasting is, I'd explain this effect as "Visibility is reduced in a rain storm, so enemies will have trouble noticing you."

It seems that the "visibility range" might decrease at rank 9, making it more effective, but I haven't yet tested below rank 9.

Also, I have not fully tested the de-aggro ability of the rain, but it seems it requires 3-5 lightning strikes.

Anyone willing to do some more testing and confirm?
