Asmodeus' Bargain

You may activate this ring as a bonus action to gain advantage on your next attack roll. Once you do so, you must take a long rest before you can use this feature again.
Any time before you regain the use of this feature the DM can have you roll on the Demonic Pact surge table immediately after you cast a spell spell of 1st level or higher. You then regain the use of this feature.
