The door opens. Such a nice door.

Yes, the door itself is fine. She doesn't really expect the answer to change from last time, but can she walk in?

Walking still stops working when she reaches the line. 

How about it she tries flying over it?

Who is she kidding, this barrier is never going to- yeah, that does the trick.

Better than the mountain ash.

"Do you need help cleaning that up?"

"If you don't mind. I do have cleaning magic, but it's not very cost-effective." 

Up comes all the caramel stuff.

"Do you want it back in the bottle or does it get used up somehow?"

"Back in the bottle, thank you. Next we can try the repulsion charm, if you'd like, unless you, ah, expect to become violent if supernaturally repelled."

"I think I can manage to contain myself."

So he'll work on that next. 

After a minute she can smell...fumes? The smell of something burning.

Presumably he knows what he's doing?

Probably. 

It doesn't look like he's burning anything, just playing with some leaves.

The smell is getting downright offensive, now, but she can probably handle it.

She can also move all the air containing the smell away from her and pull some in from further away that has been exposed to leaves.

"Amazing. Could you tell me what you're experiencing right now?"

"It was a slightly offensive odor. Now it is a pleasant breeze."

"Just the odor? No mental effects?"

"Not so far as I can tell."

"So the ones that erect barriers work until you use magical means to cross them, the one that repels only had purely physical effects, and not as strong as it usually is, either...I suppose I can try to poison you, but the effect isn't actually different from mundane poisons, so it's not a very useful test." 

"Poison would not work in general, no. This is useful information to have. My thanks."

"I'm glad to be of service. Is that all for today?"

"For me, yes. The, ah, group was planning to meet up here later. I presume they have some sort of arrangement with you about that already."

"This time I'll actually be in the building, yes. I'd rather not interrupt more than you would find useful." 

She nods.

"Speaking of useful, I don't actually have anything to do between now and when they are done with school."

"And you're looking for suggestions? I imagine with your powers, there are quite a few things you could do, depending on how prosocial you feel, and I can't help much with those. If you're looking for something more, ah, locally relevant, I can come up with something."
