Still, there's not much I can say, as Divinity did technically agree to fight the ability. I'd have asked for clarifications on its traits, so it couldn't be abused, but I have trust issues. *Shrug*
I did not agree to fight it on the terms he's slapping onto it currently. I assumed we were abiding by standard prep regulations, so I read that ability as being powerful, but not outright being able to be sustained at virtually no cost (he has cast it twice now with virtually no drawback) and against everything regardless of power. In other words, I never read his ability as a cheat sheet to use against the prep system.
Also, I wasn't talking about the division spell when I brought his shields up. I meant the shields he summoned around his character at the end of his post. But this was a very good byproduct conversation to have.
