Reverse Animation

In Desert of Exile (DoE), the Dreadlord-based hero has a Blink-like ability. When it casts it, it plays its "death" animation - as to dissipate into the air - then plays this in reverse at the target point - as to materialize.

What I want to know is how to play animations in reverse. Anybody know?

I believe it's a model edit, with an animation that is reversed.

No, you can do it, but there are some conditions. You ought to read this post of mine.
