She finds a teleport scroll

You stand there awkwardly while Siora examines scroll after scroll. Some she looks at for only a fraction of a second but others she examines for the better part of a minute before discarding. This whole time you are only getting more and more self-conscious of the shopkeeper eating both of you up with his eyes. You have half a mind to try and cover yourself up but you know it would be mostly pointless and you don't want to give him the satisfaction of acting so embarrassed of his gaze.

Thankfully when my embarrassment is reaching its limit Siora stops and shows a scroll to the shopkeeper. "I'm not fully familiar with this type of magic, but this is a teleport scroll, yes?"

The old man nods. "You are quite observant," he commends Siora. "Though I must warn you, that spell has limitations. It is only one way, and -"

"And it will only teleport our bodies, and not our belongings or clothes," Siora interrupts. "I am well aware of the limitations of this kind of magic. That last 'problem' won't be an issue for us, as you can see." She gestures to the ropes hanging across her body.

The shopkeeper chuckles in agreement. "Well, if you want that scroll, how do you expect to buy it?"

You can't help but gulp heavily. They're both right, of course. With these limitations, this scroll is more useful to the two of you in your current situation, but that exact limitation also means you don't have anything to buy it with.

Siora thinks for a minute, but eventually comes up with an idea. "I assume you have blank spell scrolls and writing material? I could craft for you a new spell scroll to replace this one."
