Detect magic reveals the aura of a flight spell around the slippers and your arcana check makes you recall reading a book in which a character wore ruby slippers and clicked the hells three times. It may be worth a shot?

With a sigh, Seren picks up a pair of slippers and in his hands taps them together 3 times to see what happens

As you click the heels together they pull you off the ground and begin to pull you uo the stairs. Please make a strength saving throw to hang on.

You can't get a good grip and you fall off the flying shoes, taking 3 bludgeoning damage.😊

“Argh! Well I found your shortcut Ruven… but it kind of sucks! What wizard expects people to be strong to get to the top?”

An exasperated voice screeches from above "Wear the blasted things on your feet!"

“Well you heard the man, Ruven. After you. Not sure if they’ll have my size and this red color completely clashes  with my style.”

With the largest smile on his face Ruven puts on the red slippers and clicks the heels together.

"I TOLD YOU!" 

Yells back to the voice above them

"When I get up there you pointy hat spell flingers! I may say thanks you!"

Puts on the slippers, and clicks 3 times. 

You both safely fly above your friend's heads and higher. You rise until you reach the third irregularly placed floor. The stairs spiral up in the center of the tower and occasionally a landing gives way to a floor, like the one you are on now. An elf, who you presume to be the wizard, is tinkering with a clock on a worktable. "Hello!" they say. "I thought there were more of you."

Seren does the shoe trick also. This time putting them on his feet.

Ruven gives the wizard a slight bow.

“Oh yes, the others should be up any second now. Thank you for seeing us master wizard. We are travelers staying at the local inn. When I inquired about getting supplies for creating spell scrolls Bevin recommended we talk to you. Would you have extra spell scroll supplies that you are willing to sell?”

Dumbfounded by the slippers Gorog puts them on wearily.

Gorog puts on the slippers and also safely flys to the wizard. "There's one more!" they say. "Now, what can I do for you?"

Ruven repeats himself.

"We would like to purchase the supplies necessary to craft spell scrolls. Bevin from the local inn told us this would be the best place to ask."

"What supplies do you need?" He looks suspiciously at Seren, him being a member of the church.

Revik also clicks the heels 3 times. 

(OOC: what supplies would Ruven need to craft a level 1 spell Scroll?)

"Well, pointy hats...at least you told us HOW to get up, BEFORE we got up...So I guess I'll say thanks.
