File:Diminishing Returns Chart.png

Summary
This image shows the first derivative of File:Ability Overview Chart.png. The x-axis is how much of an ability is stacked, and the y-axis shows what each individual ability point adds to the total stat changes. This image is an alternative way to look at diminishing returns; note how additional abilities are about half as effective when the player already has three mains.
