Projectile attributes: affected_by_rain

Arrow projectiles have an "affected_by_rain" attribute, and indeed back in 1.1 testing I measured some loss of killing power in rain (but none in dense fog.) Are there other attributes that can be added? Specifically, ones like "affected_by_fog", "snow", "wind", etc? How about "disabled_by_snow" or other such attributes? Sand storms?

Has anyone run across a list of these little gems? There is some loss of archer power in woods, quite a bit if both archer and target are in the woods. Are there any controls for this that could be added?

I would like to really nerf archery in the fog and snow, and also "indirect fire" types of archery, slings, javelins, etc. It might also help to make flaming arrows unusable in the rain (the logistics would be really awful, and the effect would be dampened--oh, yeah, I meant to put that pun in there.)

Nope, there doesn't seem to be anything else in the code.
