Sort of as follow up to the end of my last post and given the direction of Liz's last one...
We could just do a mayhem run (possibly in support of a concurrent recon mission) where we tear through the city (by which I mean going maybe a block or two into it

) killing bad guys, breaking stuff, maybe setting some traps if we have people that are good at that kind of stuff and otherwise making nuisances of ourselves, before getting out. The teleport on command spell thing would be ideal for that, though a conventional "going over the wall" method might be better for entry, just because it allows us to engage more enemies and make more noise. The teleport would also mean we could go a little farther into the city (if it doesn't look suicidal to do so and we're still in decent condition) burning and killing before teleporting out.
Just an idea.
