Art: Auras

[jdoleary]

Auras are a circular area that you can cast on the ground or on a unit. Any units or pickups that enter the auras radius gain the effect of the aura. In-game auras can be done with the particle engine.

Since there's potential for tons of aura spells (they could be their own category), the spell icon should be extremely reusable. I often tint existing icons to make new spells. Instructions for Che: this icon should be exported in layers so that the tintable parts (the aura itself) can be easily tinted by Jordan later while the background and border can be added after tinting.
