AoE Smashes
A couple of people have asked about the AoE, or Area of Affect smash. You get these skills at CS 9 and for nukers in particular it is spectacularly effective when you're getting ganged by the mobs. They also do a spectacular amount of damage, so it's only fitting that the graphic is pretty spectacular too.
The only downside to these skills is that they are very slow to level up and they cost a lot of VE to use. I'm using manuals constantly while grinding just to level this one up. The warrior smash isn't quite as useful as what the nukers get, but that's pretty much normal in this game. The warrior smash is very short range and only in the forward direction, but still, at C4 only one of my other smashes does more damage than this one so I'm trying hard to level it up.
Who else wants to post some screen shots?
