*Art: Goblin Market by Gennifer Bone made for an upcoming RPG adventure written by Megan Bennett-Burks*
There is a mysterious Goblin Market that pops up in various places around the world. Really, the market is an opening to a pocket dimension that can gate to anywhere.
The magic items are useful, and 1/4th the cost of similar goods.
The catch is that after the items are used once and later when that character fails a death save or makes a save vs. poison or death (in older editions) the character polymorphs into a goblin with no saving throw. \m/
