Charged Attack sends the player flying in to the air not the enemy, so I do not believe it would benefit from Smash Power Up. For Warriors your shield Uppercut and Rush both benefit from Smash Power Up.
For clerics, just your shield uppercut.
For mages, Magical Napalm and Lightning Strike both benefit from Smash Power Up. Thought I'd put it out there for other classes for anybody whose wondering about the benefits of Smash Power Up.
I think charged attack does also send the enemy flying if they are not killed. Not positive on that but I think it has happened to me before. And as for Ambush attack, it would be helpful when enemies are running from me and I hit them with dash attack in the back. I just didn't know how much it raises the damage and was curious if anyone knew. I would imagine that it would be more damage than attack up lvl 3, otherwise it would be useless.
