Choking Shadows

The shadow of a creature of your choice that you can see within range appears to come to life, reaching out to grab at the target creatures throat, pulling it to the ground and strangling it. The target must succeed on a Wisdom 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 Wisdom saving throw. The target has advantage on the saving throw if it's triggered by damage. On a success, the spell ends.
