I don't know if I can repeat it without restarting several times, but it seems like if a witch is hit with the electricity, it can crash the game.

@Nescius I just tried using it in the Day No Mercy custom campaign and it didn't work at all. I'm guessing it doesn't work on all custom campaigns or its a mod conflict.

It's only set up for official campaigns

@Nescius Ah, I see. Thank you for letting me know.
