Tirion's street food? What is it?

All kinds of things, some of which are recognizably sort-of-croissant-like and some which are kabobs of strange fried vegetables and some of which are harder to guess at. 

So Hero will happily eat!

"The PRT suits will meet soon to decide how best to aim you. Is there anything else like putting villains in another dimension you've thought of, as good uses of your magic?"

"Not really. Future technology might help just by making your world nicer."

"Yeah, and that probably requires less in the way of meetings of the people responsible for capes, although just distributing technology has its failure modes."

"Yeah. I can give out some of the magic, but that has a lot of failure modes."

"What magic can you give out?"

"Uh, the songs I can give out really easily, just a recording. The teleport and the healing I could make an artifact that'd let someone else have them but it'd take me a long time and we don't usually share them unless we're really sure of someone, there's - a way they could get misused - it might depend on whether there are other telepaths -"

"There aren't any other telepaths," Hero pauses eating to put in. "Some people theorize telepathy's impossible for parahumans."

"Then it might be safe because I could be pretty sure the people I gave it to couldn't themselves give it out."

"You can only give magic via telepathy?"

"Depends on the kind. The healing spell and teleport you can only give via telepathy and the artifact I'd have to make, so I'd have two ways of making sure it didn't get out of control."

He nods. "So worst-case you could give the healing spell to people who definitely don't have telepathy?"

"...no, if other people had telepathy and could get it from them that'd be a problem too."

"Oh, you can get it from other people like that, hmm.—wait, are you protected from telepathy, too?"

"I'm protected against my kind of telepathy. I don't know if I'm protected against other kinds of telepathy, probably not, but the more people we give it out to the more points of failure."

He nods and—

—Legend looks at him—

—he grins and resumes eating.

"In any case there aren't any other telepaths that we know of. What are the problems with distributing the healing spell, other than potentially giving villains access to healing spells?"

"The healing spell can't be distributed without its building blocks which could potentially be reshuffled to do - well, anything, that particular magic system has no hard constraints."

"No hard constraints, as in, you can do literally anything with it?"

"Yeah."

"What's the bottleneck on generalized omnipotence?"
