Here's a short video of the new shadow priest spell called Shadowy Apparition.

Here's what I'm doing in this video:
1. Enabling "walk" mode
2. Walk around while using mouseover macro to dot up all the dummies with sw:p
3. Targetting one dummy
4. ???
5. Profit!


*Update*
This spell has been changed and the shadows wont only attack the current target anymore and the spell animation is completely different.
