OK Ive got a slightly adjusted solution for anyone else playing around with this.
Pretty cool. Unreal continues to be fascinating to use.
This is the blueprints I used.
The niagara system.
With this you can chop and change as much as you like with events etc. Pretty sick.
Ps. Unreal if you read these, It’s difficult to figure out what’s working and what’s not between the Niagara system and blueprints, it doesn’t throw errors if something doesn’t match and finding applicable Niagara nodes without already knowing what to search was difficult.
