Nightmare adaption

[Stippy]

Hey @all,

really love the new shadow units, they open up new plays quite a lot.

For Nightmare, I fell like the animation is a bit missleading in a sense. It seems like an explosion, but there is no typical explosion effect there. A simple improvement would be to change the explosion animation into a more "aura" or "poison" style animation. Like purple smoke.
 

But what I would suggest is to add a knockback effect for S targets. That would enhance the functionality a bit and work better for the animation. Perhaps, to not make it too strong, have a smaller knockback radius than debug radius.

It is true that a more poison like effect might better communicate what is happening than the present explosion which could be confused with a damage effect.
