At the start of your turn, make an Intelligence saving throw (DC 20) as an action. On a success, the creature solves the cube and has advantage on intelligence checks for the next 24 hours. On a fail, the creature can't take a bonus action and must continue to attempt to solve the cube on their next turn.
