Temperance does want to watch that. And take notes. "Do you get some sort of feedback from ending the magic early? Is the rest of the energy wasted? Can you do it at a distance?"

"Ongoing effects kinda... Stay in the back of your head? I can pick one and cut it out. I don't get points back."

"Do they require any sort of concentration that would be disrupted with sleep or a strong distraction like a pain or loud noises?"

"Nah. You can accidentally drop one but more like accidentally putting down the thing you went in a room to get in the first place, than being startled and dropping something."

"So, at least somewhat related to presence of mind. Are you aware of what effects related to a given sensation? Could you accidentally get confused and cut off the wrong effect?"

"Things keep going if you fall asleep or something. Mostly. And, I dunno."

"What about range? Do you need to see something to affect it? Would it break if you moved far away?"

"Depends. Seeing the target is pretty much mandatory, yes. I don't know about the breaking thing? Potions don't break, but they've all got black in 'em and not breaking is kind of black's whole thing."
