As a Reaction when you see a creature attack or move, you clap and cheer, forcing them to repeat what they just did. The creature must roll a Wisdom saving throw. On a failure, they immediately use their Reaction to repeat the movement or attack. If they were moving, they move the same distance again, travelling in the same direction they were at the end of their movement. They stop if they reach an object that blocks their way or when continuing would cause them obvious harm. If they were attacking, they attack the same target again with the same weapon. An ally can choose to fail this saving throw.
