Electric Surge

You cause up to three targets within range to erupt into electricity. Each target must make a Constitution saving throw or take 1d6 lightning damage. In addition, every creature within 5 feet of an affected target must make a Constitution saving throw or take 1d6 lightning damage.

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