Hunter's wind

I don't have a pretty picture for this. :'(

The concept is that the Freljord has a breeze that blows from top lane towards bot. Players emit small particles of energy into their surroundings. These particles can be transported by the wind through the channels of the jungle and river for a limited distance. Particles can be seen by friendly and enemies alike. If a player is hiding in a bush, the particles will not be taken by the wind. Bushes down-wind will block the flow of particles

Particle size and/or density is based of AD/AP/Life ratios. Armor and MR will reduce particle volume.

The particles do no damage.

This could be a global effect, jungle buff, or an item.
