Celestial Protection

You call upon your deitety to protect you from spiritual damage, lessening its effect on you and reflecting it back upon your next spell attack. You have resistance to the triggering damage type until the start of your next turn. Additionally, add an extra 1d6 damage to your next spell attack, then the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the extra damage increases by 1d6 for each slot level above 1st.
