Help with a new ability

[Magyka]

Id like to figure out if this ability is even possible, and if it is, some tips on how to do it.
First it will do a thunderstomp like animation that also stuns for 2 seconds, then a bladestorm for maybe a second, then a knockback about 5 feet. Any help will be awsome be it GUI triggers or JASS or just regular abilities

Ok cool, i got everything except the part about the set temp_point = (position of (casting unit))

[Aero]

Still leaks temp_point.
And Point offset by ... ect.

That's a PolarProjectionBJ call (Which leaks a location every time it's called)
