I’m getting the hang of it a little bit. Yes, that person uses a template gas emitter to copy attributes from, and then deletes it. Still, it is like 99% from scratch. This is the Rosetta stone of Niagara fluids. I’m so grateful for it. 
Thanks once again for your help and time.
Now, the only question is, how do I sample the 3D density texture to see if the player or enemies are in the way of fiery or lightning streams? No Marching Cubes required. LOL
