Avaritia

You inflict a target with an insatiable desire for more. The target must make a Wisdom saving throw. On a failure, they are cursed with a constant desire for excess. This affects their decision-making, causing them to act irrationally and make unwise choices. The target has disadvantage on all Wisdom and Intelligence checks and saving throws for the duration. This curse cannot be lifted by normal means and requires a remove curse spell cast at 8th level or higher.
