Warden's Rebuke

You lash out at the attacker within range of your weapon. Make one weapon attack against the triggering creature. On a hit, the creature takes normal weapon damage, and the triggering attack's damage is reduced equal to your Wisdom modifier (minimum 1).

At Higher Levels.
When you cast this spell using a spell slot of 2nd level or higher, the damage reduction increases by 5 per slot level above 1st.
