Effect works great in-game and looks incredible! I might use it in a project I'm working on.
EDIT: I wanted to note, you can create a rudimentary, scorched ground, after-effect by creating a modified destructible, and using Create- Destructible at instead of Create- Special Effect at in the trigger for the ground unit. Pretty much just a leftover shadow that can be walked over, but may also be useful and is easy to replicate.
Also, not sure if that creates leaks but I included attached screenshots and sample map of modifications needed to demonstrate.
