Re: Diffuse body of swarm with scatter enhancement, and AOE attacks (Mainly Explosion
Calculating area is pretty simple, actually.
The Body of Swarm is spread out over a radius of R. That's an area of πR^2. The attack has a radius of r. That's an area of πr^2. The ratio of areas is πr^2/πR^2, which simplifies to r^2/R^2, or if you prefer, to (r/R)^2.
So, for example, if the swarm has radius 100 yards, and the explosion has radius 20 yards, the fraction of damage is (20/100)^2 = 0.2^2 = 0.04.
