Cage Mind

You choose a creature you can see within range and cage its mental faculties if this spell affects it. The target must succeed on an Intelligence saving throw or fall prone, becoming incapacitated and unable to stand up for the duration. A creature with an Intelligence score of 4 or less isn’t affected.

At the end of each of its turns, and each time it takes damage, the target can make another Intelligence saving throw. The target has advantage on the saving throw if it's triggered by damage. On a success, the spell ends.
