Brittle

You freeze a non-magical weapon held by a creature that you can see within range, causing the weapon to become extremely brittle. The next time the weapon is used to make an attack, the creature holding it must succeed on a Dexterity saving throw or the weapon shatters and is destroyed after the attack is resolved. If the saving throw is successful, the weapon is unharmed and the spell ends on that weapon.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can target one additional non-magical weapon for each slot level above 2nd.
