More skill variety in visual and function

Some of the skills look and work very similar. Some of the support skills make the active skill change. There are some skills that look like the same skills and have a little difference in effect.

For example: Sunder, Glacial Cascade, and Unearth all look like the same skill. They work a little different, but visually looks like the same skill and even the shape of the area of effect is similar.

There should be more variety in skill visuals and in function.
