Attacker's Folly

You sap a combatant's strength and cripple its ability to do damage. Choose one creature that you can see within range to make a Strength saving throw. If it fails, the target's melee attacks do minimum damage for the duration. At the end of each of its turns, the target can make a Strength saving throw. On a success, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the duration increases by 1 round for each slot level above 2nd.
