After last session in my FWTD campaign, I joked that I'd give a free level in Subway Fighting* if they bring me a clip with them practising it IRL for at least 15 seconds.
I didn't expect anyone to take the offer. However, it seems I was wrong.
I'm actually glad I didn't offer them a free level in Seduction, the clip might have been awkward!
Still, what are your players ready to do for a free skill?
*That's the skill in the setting of using the trains and the momentum of the moving subway to your advantage.
