Curse Object

You cause one no-magical object to become cursed. The effects of this curse are triggered when the object is worn or carried for more than one minute. When you cast this spell, choose the nature of the curse from the following options:

• Choose one ability score. While the curse is active, the target has disadvantage on ability checks and saving throws made with that ability score.
• While the curse is active, the target has disadvantage on attack rolls against all creatures of a type specified when this spell was cast.
• While the curse is active, the target must make a Wisdom saving throw at the start of each of its turns. If it fails, it wastes its action that turn doing nothing.
• While the curse is active, the attacks and spells of a specified creature type deal an extra 1d8 necrotic damage to the target.
  
  

All objects cursed in such a way cannot be removed or left behind willingly by the creature that activated the curse.

A remove curse spell ends this effect. At the DM's option, you may choose an alternative curse effect, but it should be no more powerful than those described above. The DM has final say on such a curse's effect.
