Auction Encounters

From publisher blurb:

Auctions replace the dull sessions of “Shopping the RPG” and setting breaking Ye Olde Magik Item Shoppes. They provide opportunities to introduce NPCs, drop plot hooks, or add complications to your story. They can be dynamic settings requiring more than a swing of the sword or a well-placed fireball. Auction Encounters introduces a system that uses existing 5e rules that players are already familiar with, no new systems required.

This 40-page supplement includes 7 NPCs and 7 one-sheet adventures that incorporate auctions. Rules for running auctions and pages of information to create your own auctions and use them to serve your ongoing stories.
