Player ability blueprint help

Looking for some help while learning/creating my game. What I would like to do is have a spell outline flash when the player holds an input down, while able to aim it, then cast the ability where they aimed the ability shape. Much like the game Wildstar. Should I use emitters for both or decal then emitter? Does anyone have a picture of the basic blueprints needed to do this that I could mess around with for each ability? Any help appreciated, thanks in advance.

This was free not sure how much is now also many tutorials on Youtube on how to do this or a basis of that.
