...Two questions that I'd like to ask.
Firstly, does it have a tell? If this effects enemies who use this attack, is there still an animation showing where it'll strike, like base game, I think? I'd like to know where it'll strike before it hits me. It seems cool, but I'd rather not unexpectedly get hit by it.

And second, Repentance compatibility, but someone already asked, so...

...Y'know, I had something like this in mind.
But it was the Undertale "Shocker Breaker" attack from the final fight. It seems like it'd work for this sorta thing.

I wouldn't mind that as just a sound mod, at least.

Works in Repentance?

@Luni
Since lightning bolts carry massive amounts of heat/energy I think it is fitting that little scars be left there. But that's just me.

great mod but the permanent smear on the ground makes it seem as if I bombed, would be cool if it vanished over time

Ummm...
