How do I change a unit?

Try specifying the path to the visual effect of Armageddon here (I did this once to make the hero's regular attack trigger a meteor strike and Armageddon).

😅 yeah... and I guess I wasn't even close to looking in the right place. I'll try now... (but now I understand when and where I found it).

Thank you, progress has been made. However, the question remains: how to make it summon a projectile for each enemy, not just the main target. I hope I'll figure it out...

*This is where the idea for the lightning came from. A long time ago, I had a mod called "Gods" or something similar, where one of the human unit upgrades gave them an AoE attack (like the Dancers, including ranged attacks), and when Monks attacked multiple targets, it would summon a "meteor" for each attacked enemy. It looked cool, and that's when the question arose: "What if we increase the scale?!"
