Looking for a more complex push ability

[TheIlluminator]

Basically, I'm trying to find a push ability that can push the target through (and knock over) trees, but above that, to be able to deal damage, say, per tree knocked into, and/or amount of time not moving (like if the target hits a wall, basically, the more time they aren't moving, that would mean that much force was what they hit the wall with.

If anyone interested in making something like this needs some sort of clarification as to what I mean, just ask.
