While attuned and wearing the ring, you can gain advantage on one ability check of your choice. The ring can’t be used this way again until the next dawn.

Curse. Once attuned to the ring, the character is cursed. The cursed individual can under no circumstances believe the ring is cursed. All attempts at convincing them otherwise automatically fail, despite any normal reaction to any information.

Any individual that travels with the cursed individual for longer than two hours comes to the understanding that the ring is cursed.

Any attempts to discern the ring's curse while it is not attuned to fails, and any attempts to figure out the ring's curse afterwards come out inconclusive.

Additionally, after you use the stone’s magic, your next ability check is made with disadvantage. The attuned individual does not take note of the disadvantaged state.
