While they aren't cursed items in the traditional PnP sense, the game still has a handful of malicious items that will turn against its user/wearer when certain conditions are met.
- The Necromancy tome which will reduce your ability score (I think it's either Intelligence or Wisdom) if you try to uncover the book's dark secrets but fail the associated skill check
- The hag's mask which will possess your character if you put it on
- The gloves of the absolute or whatever their name is. These magic gloves will apply Bane to any enemy you hit if you're branded with the mark of the absolute, but if you don't have the mark and still try to use the gloves, you'll be the one getting Bane'd instead.
While I don't know if we'll get 'real' cursed items I'd say it certainly seems like the game isn't opposed to the idea of handing you items that will work against you.
