Wow!
I just did a D/L on your latest version here. And here's a screen of my first hit with this mod. Zoomed in on an F12 view, and you can even hear the flames!
I watched the effect from the first eel hit, then to the next 2 that followed; very convincing effects, even to the final flames and slick residues, smoke smoldered and drifted to the last moment of flames, and up it went! Funnel smoke trails are all the best now, both day and night. Super job here.
