How to add a script to play an animation when a spell is cast?

[valencia]

I'm in the process of making a very cool Evelynn (from League) themed PSQ transform pack at the moment. But the only thing missing is adding an animation to PSQ's transform spell.

I have some cool animation that I want to hook. Problem is if you search on the web, you find little to no information on hooking animations to spells/powers. I really wish we had some kind of documentation about everything in the Creation Kit. The Wiki is missing a lot of info. can someone please tell me how to do that?
