"Sounds good. So the benefits are healing, new sense, ability to hand out the artifacts you've touched, probably the mental opacity thing, languages, and the drawbacks are blind+deaf, music allergy, overheating, the teleport, and - does that mean blind and deaf are probably separate -"

"No."

"It doesn't?"

"There's, there's another bad one, psychological effect, if I hand out powers by drawback it won't affect anybody."

"...okay."

"...um, who should I try stuff on."

"...I'll ask for volunteers."

She does. She gets one.

And Annie hands out powers by drawback.

Warmth: no obvious correlate at all.

Music allergy, once they can get everybody to quit singing long enough to test it in case it depends on the species of the effect bearer: healing.

Blindness: packaged with deafness and the sense of smell loss after all. Comes with the weird sense.

Everyone is very disappointed that the healing comes with the music allergy. ...the warmth not having a correlate means there's another drawback too, one they haven't noticed yet, right? In addition to the one she's not discussing in much depth.

Yeah it does. At least one. There could be lots of hidey ones.

Fantastic.

So they can't make many inferences about what goes with the other ones. There's mental opacity and the power-handing-out itself to account for, and one more without discernable effects...they ask their people who'd want a teleport to a random world. Most people do, but - not quite yet. Once the Enemy comes for them. 

Okay.

...In the meantime the healing might do old injuries and it does not seem likely that removing it would reinflict them. If Rirosseth or anyone else would like to borrow it for just a short musicless period.

"That's a good idea, but."

She has flashbacks when touched.

Oh.

(Substantial fractions of the contents of Annie's brain tear themselves to shreds because Rirosseth must never ever ever come to harm.)

"Um - maybe if you were sleeping or something? It doesn't feel like anything, healing..."

"I can handle it, I would just - need to be prepared. Maybe tomorrow."

"Okay."

"...you okay?"

"I'm fine."

"Maybe the drawback or drawbacks we're missing will make itself manifest."

"Maybe."

"Thank you, Annie. This is very good news even if we can't have it all puzzled out instantly."

"You're welcome."

And the next day she will be able to poke Annie's finger with hers for healing. She looks like this is absolutely terrifying.

Oh no poor Rirosseth oh no. Annie does her very best to hold still and look unintimidating. Healing goes.
