I have a great idea for a campaign that's roughly based on the Jackie Chan Adventures TV. They got to get the 12 talismans with one talisman per level with those talismans being the magic items.
Great item to throw in a random loot pile. Can fit in a pile of any creature of any CR. Why is it there? It was part of different treasure and no one bothers to use it or get rid of it. It's a dungeon white elephant
