The Curse card performs the following depending on the power level.
- Power level 0: Curses 1d2 items in the player's inventory.
- Power level 1: Curses one or more items; after each item cursed, there is a 75% chance that it will curse another. (On average four items may be cursed by this, but with bad enough luck an entire pack could get cursed.)
- Power level 2: As power level 1, but the chance of continuing is 99.9%.
The Curse card could be found in the following decks over the past several versions.
